RE: Towing mileage/capability

Bruce, in reading your post carefully it appears that you're looking for something that's easier for your wife to get into. That pretty much rules out another full size SUV or pickup. There's lots of guys on here who think you need a full size pickup to tow anything with wheels on it. Your weights you estimated are likely to be spot-on, your trailer's GVWR is a shade under 4000. Basically a smaller ultralight, certainly not needing a full size pickup. I used to tow a larger ultralight than yours with a Ford Aerostar, and it towed pretty well despite having much less power than today's vehicles. I think the Ford Flex or similar mid size SUV you mentioned might work well if you're careful about what you pick. Forget about FWD, AWD is the way to go. You also need to make sure that whatever vehicle you pick has adequate payload, a factory tow package, and a receiver that can be used with a weight distribution hitch (not all can). Get one with a real transmission- not a CVT. Get the most powerful engine in whatever vehicle you pick- the 2.7 Ecoboost available in the Flex is also used in the F150 and would have the power to tow your trailer easily. Don't look for any improvement on towing mileage though, it's going to suck unless you use something that burns diesel. Then it will just suck less.

RE: MPG for transit based motorhomes

That is decent fuel economy. Too bad that chassis is offered only with a SRW axle. A DRW would have done the chassis wonders. I've seen this comment regarding this chassis from you before and wonder why. The Promaster chassis is front wheel drive, and it would be silly to put dual rear wheels on a front wheel drive chassis to load the rear axle heavier. These trucks, when their axles are fully loaded, have about a 45/55% F/R weight bias. RGAWR on a Promaster is well under 6000 lbs. Single rear wheels handle these weights easily. If you bump that up to a 7K+ RGAWR on a FWD chassis, you're not going to go anywhere when you're fully loaded. Now, the RWD Transit and Sprinter chassis, benefit from a DRW axle since they carry more weight in that configuration. But the DRW Transit does not have a wider rear track than the SRW, unlike your E350, so the DRW Transit will not have the extra stability a that the wider track of the E350 or 450 DRW.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Cybertruck with shorter 16ft Airstream Basecamp : https://live.staticflickr.com/65535/51815527580_ca50e6e7c6_c.jpg That would be a great fit for the Cybertruck or other EVs, small and aerodynamic enough to not reduce the vehicle's range to an unreasonable distance.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

https://live.staticflickr.com/65535/51800421476_2c293da5ec_c.jpg video This guy has some great points, however one he is missing is the utilization time of an over the road truck- a truck isn't earning if its wheels aren't turning. A team-driven diesel semi can be rolling up to 120 hours per week and can go 1500+ miles without refueling. Even after a robust commercial charging network is in place, electric semis will need to stop every 400 miles or so for a recharge. I don't know what the charge times will be for the semi, but until the down time for recharging is similar to that of a diesel truck for refueling, they won't be able to match the productivity for over the road. Now, for local work it's a whole different story, I can see electric trucks beating diesels hands down for operating costs.

RE: Tesla with a generator on a hitch haul

rjstractor, I found 24 kw to move 100 miles, on the wobbly wide web. (model 3 Tesla) However I did not know that when plugged in the tesla won't move. I guess that is a good safety feature. Don, a Model 3 doesn't go 100 miles on 24 kilowatts, it goes 100 miles on 24 kilowatt/hours. I think you're confusing the concepts of absolute power output (kw) and power output over time (kw/hr). It's kind of like the idea of torque and horsepower. ........ Again, please use the correct units...particularly if you are correcting the use of units. 24 kw/hr implies if you start from a standstill the power output will gradually ramp up from 0kw until an hour later it will be at 24kw (assuming you continue for an hour). In common usage, it's a nonsense value that has no real use. The correct units are kilowatt hours (KWH). My most sincere apologies for adding an extra 'r'. You know what I meant, an output of 24 kw for 1 hour. Is that not what a kwh is?

It's kind of like the idea of torque and horsepower. Since the car takes 24 kw/h to go 100 miles, that little generator would need to run for just over 9 hours at 2.6 kw to produce that much power. So the car would be moving at about 11 mph. That's assuming it was able to put all that power into the car battery, which it can't. To move the car at highway speed (60 mph) for 100 miles, the generator would need to produce the 24 kw/h in 100 minutes, which requires a generator with a power output of 15 kw. That's a pretty big generator to pack on a hitch hauler. :B

RE: Tesla with a generator on a hitch haul

Tesla uses 2.4 kw per mile at highway speeds. The generator could keep up with that, since it does about 2.6 kw. Gary thanks for the link. I'm not sure how you came up with that, but your math seems a little goofy. 2.6 kw is just over 3 hp. It takes a lot more than 3 hp to move a 4000 lb car at 60 mph, regardless of how efficient it is. My math came up a little different. I googled that the average Tesla uses 34 kwh per 100 miles at highway speeds. That's 340 watt/hours per mile. In one hour at 60 mph, you obviously travel 60 miles, so 340 watt/hours x 60 = power consumption rate of 20.4 kw. That equates to just under 28 hp, which sounds much more reasonable to move a 4000 lb car at 60 mph.

RE: Stability control

Your unit has too little caster. Not very helpful, as the OPs motorhome is on a Mercedes chassis. To the OP, I haven't seen too many handling complaints about the Mercedes chassis. Part of may be your expectations, depending on what they are. Although some say they do, these things don't drive like SUVs. Have you owned other motorhomes? I haven't seen anyone mention weights. GVWR is pretty low for a motorhome this size, and it would not take a huge overload on the rear axle to make it handle terribly. I would start by knowing your weights.

RE: GMC Ecotech engine

That seems odd that the 1.5 turbo four felt gutless in the Malibu. 160hp/185tq should be plenty of snort to move a 3200 lb car right along. My VW AWD wagon has just a little bit more motor (1.8L, 170hp 200 tq) but it's 300 lbs heavier as well. It zips right along, 0-60 in the mid 7s and will cruise easily at 85+. There are cars that are faster for sure, but it's far from sluggish. Maybe the one you drove was just a turd? It takes a bit of a change in thinking but with DI turbocharged technology, 1.5L is no longer a tiny motor. Sort of like how a little 2.7L V6 in an F150 will run away from the twice-as-big V8 used in the F150 15 years ago.

RE: It's time to winterize...

^^^ Good explanation Rick, there are misconceptions about what GFCIs do and don't do. To the OP, I don't see any concerns using a space heater in a motorhome as long as everything is up to par, and with a 30 amp service it likely is. It's no more likely to cause a fire than using a space heater in your house. I don't know what happened in your cousin's case, but in my more than a few years in the fire service, most space heater fires are caused by items too close to the heater. Sometimes they cause issues if there is faulty wiring due to the high current draw (actually happened to me in my house), but if your wiring is good you should be fine using a space heater.

RE: Truck of the Year

Fuel cost on my class c are 33 cents per kilometer or 53 cents per mile. A Bev is a factor of ten cheaper. I'm curious to see your math. It seems exceedingly optimistic. From what I've read, to move an EV the size and weight of your motorhome at speed takes on the order of 1.5 kwh/mile. With an average cost in the US of $0.14/kwh, you're looking at a factor of about 2.5 cheaper, not 10.

RE: Condor motorcycle dolly?

I've never seen one but it looks like it could work. The only issue I can see is that the underside of the dolly might hang up as it breaks over from the ramp to the trailer deck. It looks pretty low. I'm interested because in the next year or two I'll be buying a travel trailer of some type and am looking at options for bringing my 2020 Heritage Classic along.

RE: Tesla Cybertuck - Can we take another thread?

I read a thought provoking jab at EVs this morning, something I never considered. Not trying to stir anything up, but out of lack of knowledge, it makes me wonder. Let's suppose ICE vehicles are gone and it's all EV. I'm sure we have all been in a situation where there is a major issue on the road, a bad wreck, a weather problem, whatever. The highway is closed for many hours while they address the situation, perhaps even overnight or longer. And its January. You and everyone else is sitting there trying to stay warm and you have a 3 mile lineup of EVs with dead batteries.... How good are the heaters in an EV, and how much power do they draw? How do you rescue hundreds of motorists and clear a highway full of dead battery vehicles? Maybe the solution is simple and I don't see it... In that kind of situation an EV is a pretty good place to be. AN EV heater keeping a car warm draws less than a KW. A typical EV has a 60 to 100 kWh battery. You could sit there warm and cosy for days with no problem. The upcoming half ton EV’s have batteries between 140 to 200 kWh. You could probably stay warm and comfortable for a week in those. Same in summer with AC. Doesn’t take much to keep a warm car warm or a cool car cool. Agree with Reisander on this one- A pickup with a 25 gallon tank uses about 1/4 gallon per hour idling and an EV with a 100 kwh battery will draw about 1 kw to keep the car warm. Either way, with a full tank or battery you have heat for 100 hours. Takes a whole lot more heat energy to move a car down the road than it does to heat it. It's easier to use a gas can to get an empty ICE vehicle going than getting a dead EV going, but they tell car drivers to be mindful of their fuel level before heading over a pass. EV drivers will need to do the same. But a 4-6 hour pass closure should not be an issue.

RE: Tesla Semi truck unveil & test ride set for Oct 26th !

Semi New Megachargerss Taking the cudgels from @fj12ryder and @dadoffourgirls -- so many mega chargers and so little Tesla semis. And for us where hope spring eternal, wish Cybertrucks towing RVs will have access to these pull-through chargers. It would only make sense. It would make a lot more sense for any EV to be able to charge quickly at any charger. For this whole EV thing to really work, the industry needs to figure that part out.

RE: towing with ev6

Hi all, First, I know almost nada about towing. Kia has come out with the EV6 with an over 300 mile range. It has a towing capacity of 1600 KG (3527 lb). Share your thoughts? Lots of EV towing videos out there. The Fast Lane Truck has done a few. I'm pretty interested in EVs and try to look at them from a science-focused lens. (weird, right?) Bottom line- EVs are considerably more efficient than ICE vehicles when not towing. The downside of that is that a trailer takes exactly the same amount of energy to move it down the road regardless of what's pulling it. It seems counterintuitive, but the result ends up being that the efficiency of an EV while towing is hurt much more than a comparable ICE tow vehicle. Bottom line, figure that the EVs range while towing at capacity will be 1/3 that of its solo range. I've read and watched several EV towing tests that bear this out.

RE: Motorhome Fuel Economy

No several others have similar fuel economies, so overall not that unusual. Remember their Diesel not Gas Motorhomes., the diesels get vastly better fuel economies and much greater reliability than in the US, under non NA regulations, bit like comparing Oranges to Apples.See the other posts on the FB website, similar fuel economies. None in their right mind here would run a gas powered motorhome, possibly a LPG conversion but not a Petrol one. Yes, I understand that these motorhomes getting this alleged mpg are diesel. I know you hate gas engines, and that's ok. I like diesels. I own a diesel pickup. It weighs about 7000 lbs., and at 60 mpg on flat terrain it gets 20 mpg all day. It's older but is in excellent mechanical shape and has no emission controls. My buddy has a Mercedes Sprinter diesel class B motorhome, and he doesn't get anywhere near 26 mpg. Maybe Australian math is different?

RE: Motorhome Fuel Economy

Ah, if only I could get double digits in my C....10 would be great. But I live between 7 and 8 depending on if i'm pulling a dinghy or not, and speed, and wind, and.... I've never gotten above 8.3. 33 foot C. Loaded. I expected more like yours, anyway nice to see 25.8US mpg for a nearly 26ft,11,000lb GVWR Motorhome This is also pretty stunning 16.8USMpg towing a Suzuki Jimmy We average 14/100(16.8 US mpg) 2020 iveco avida Esperance upgraded weight 5200 towing a Suzuki Jimny I think the 16.8 mpg towing a Suzuki Jimny is much more realistic. A small, light towed vehicle should hardly affect fuel mileage. When I had an E450 based class C, of course it got much worse mileage, but towing a 3200 pound vehicle cost me less than 1 mpg. As far as getting almost 26 mpg in an 11000 lb motorhome? I think they adopted in Australia the time-tested American method of increase fuel economy- make up numbers to impress the internet! :W

RE: Rivian towing efficiency

I read the test also, and it affirms the towing results I've seen from tests of various Tesla models- moderate towing cuts an EVs range to somewhere between a half and a third of its solo range. A prospective EV owner who wants to do serious towing should think in terms of KWh per mile, not advertised range. The Rivian towing a modest size load consumed power at about 1 KWh per mile, a huge increase in power consumption compared with its EPA estimated range figures which pencil out to about .43 KWh per mile. Towing a high wall travel trailer I imagine would increase the consumption to 1.25-1.5 KWh per mile, cutting the truck's range to under 100 miles. I look forward to seeing a tow test with something like a high profile bumper pull toy hauler, which would be within the Rivian's tow rating, but takes a lot more power to move it down the highway than a car on a flatbed trailer. The main issue with EVs in a towing application is not performance or power, it's range. It's going to take a battery in the 500 KWh range to enable an EV to tow a significant load long distances between charges.

RE: Flat tow toad brake and tow bar recommendations

You could use a Tow-Dolly with breaks, surge or electric. If he dolly tows an F150, the only thing that "breaks" is his truck. The 4WD model can be towed four down.

RE: Renting My Truck Camper

Do you think there would be a market for people who want to rent a camper like this at a specified location and not necessarily move it ? For example, client wants to go camping, they book themselves a campsite for the week, i transport the camper to the campsite for them to use, they dont drive anywhere, they use it , when they're done i pick it up. Maybe they want to see how it feels to live in sucha vehicle, maybe they want something different and unique. Or is it unrealistic to expect that someone who rents a vehicle on wheels is not going to want to use the wheels ? lol I read your post carefully (not everyone does that, it's obvious from many of the replies), and from what I read you are proposing is dropping off and setting up the camper for a client, and then picking it up at the end of the rental. There are many people who do that with travel trailers, and I imagine one could be successful at that. I don't think it would work nearly as well with a TC. Why? A renter would have no interest in the advantages of a TC (the ability to tow a trailer and/or go off road) and only be left with the disadvantages (a tiny amount of living space for the cost of the RV). The biggest, most expensive TC has less living space than even a smaller travel trailer, but costs more, making it necessary to rent for more $$. If a renter is just wanting a parked RV to camp in, why would they want to rent a relatively tiny TC instead of a 30' travel trailer for the same rental fee?
