RE: what size inverter.

my microwave draws 1565 watts. 1500 is not going to cut it for me. wow, is that a comercial restuarant model? I havent seen one rated over 1100 and that being one of the biggest ones, most I see are 900 to 1000. Microwaves have two spec's on "watts". the advertized one, which is usually the OUTPUT power, then on the back plate the actual power draw from the line. The first is commonly in the 1000W range, the second is usually in the 1300-1500 watt range. At least in the U.S. if current draw exceeds around 12A they need to be equipped with a 20A plug rather than the common 15A plug. That pretty much limits them to 1500 or so watts actual power draw. Then there is the power draw and VA. Since they are not a resistive device and usually no power factor correction, the current draw (which inveters care about) will usually be higher than derived from assuming a resistive load.

RE: what size inverter.

As they said 300 watts for Entainerment/computer only 1500 is the absolute minimum for a Microwave I'd go with 2,000 Panasonic true inverter microwaves run just fine on a 1000W inverter if you set power to 50% max. Done that for 8 years now. yes, things take a bit longer (maybe 50%) to heat, but that's it. 50% is drawing about 750-800VA, you can actually go to 70% or so if you have a big enough battery bank and are reasonably charged. 50% works on a set of 4GC2's discharged to around 50-60%. Now a conventional microwave, yes 1500W minimum.

RE: what size inverter.

Ok so building another battery and I am wondering what the smallest size inverter people would run in a camper. I am thinking if I get a 1500 watt inverter and if I decide to put a microwave in at some point then get a smaller 700 watt one. is a 1500 watt inverter proacticle for most normal stuff? the reason I am looking at that siaze is that is about a 125 amp draw so I can go with a 150 amp BMS and not be running flat out. Steve depends a lot on what you want to run. If it's only a TV or other low draw appliances, 300-500 or even less may be adeqate Want to run a microwave, 1000W is enough........ ok the flames will begin with "can't run a microwave on a 1000W inverter". Well stop by, I've done it for 8 years now, easy peasy. All it takes is a panasonic true inverter microwave, run it at 50% power and that's what it draws, non of the 100% 0% 100% stuff. And at 50% it doesn't take twice as long, maybe 50% longer. BTW panasonic makes a true inverter microwave that is a drop in fit for the vast majority of RV microwaves, and it's a much better microwave overall than the typical RV microwave and a decent price. And along with that, we run a 800W Keuring coffee maker on occasion, (the one you often see in hotel rooms) and we have a travel hair dryer with a 750W and 1200W setting, stick with the 750 W when on battery power. Now if you want to go whole hog, 1500-2000W will cover most anything assuming you can put in a battery bank, wiring, and inverter location to support the 4/0 cabling.

RE: Leaking fresh water tank

Sorry for not getting back sooner but I wanted to make a trip and make sure my repair was sound. My spin weld guy flaked out on me so I contacted a RV dealer near by that was recommended and he welded it for me. $200! I wanted a new tank but I guess they repair them all the time as some had advised me here.Little pricey but what isn't these days? Thank you for the help! the vast majority of plastic fresh water tanks are a material that is easy and best fixed by spin welding. Holds up great. In fact in these tanks most of the fitting that aren't molded in are spin welded at the factory. Most repair shops that do spin weld repair have an assortment of spin weld patches on hand. Basically the patch or fitting is spun against the tank and friction melts the junction, stop, let it cool and it's welded together. For black/grey tanks, most are ABS which again is easy to fix, but instead of spin welding, solvent welding is done. Basically either use ABS glue on small cracks or use abs sheet material to bridge the break and solvent weld.

RE: Moving spots at RV park ? about weight distribution

as long as your within the weight carrying capacity of of the reciever, (many recievers have a weight carrying limit that is less than weight distributing) not an issue IMHO. I move my trailer from the RV lot in our neighborhood to the driveway and back w/o hooking up the WD.

RE: Electric tongue Jack blows fuses

The fix is easy. Just don't do it. Electric tongue jacks are unreliable. I have a new jack in the garage that was replaced by a manual crank type. The Electric all are subject to moisture intrusion in the switches. 25 years of use of electric tongue jacks, probably 50-100 times/year, two trailers= 50 "trailer years of use" Electric tongue jack failures= Zip. Can they fail? yes, but I'd hardly put them in the "unreliable" category. And when I have 1500 lbs on the tongue, manual jack is NOT to my liking.

RE: Electric tongue Jack blows fuses

What y'all are saying makes sense.... But,this is my 4 tt with electric tongue jack over 20 years and this never happened. This isn't some new behavior of mine that suddenly appeared. 2 Atwood jacks and an ultra-fab 5500 prior to this Barker. If the other jacks had behaved this way, I wouldn't have this this **** habit. I guess this is a character builder, eh? The atwood I had on another trailer behaved like the Barker. change direction quick before it completely stops= blown 30A slow blow fuse.
ktmrfs 09/18/22 09:32am Tech Issues
RE: Electric tongue Jack blows fuses

Dont think in all my years I ever saw a jack with a fuse. I just put an electric jack on my car trailer and the instruction had me wire directly to the battery. My landing gear on my 5th wheel has self resetting a circuit breaker in line but thats the most I ever saw I've had 3 different electric jacks over the years, all came with a 30A fuse wired into the pigtail.

RE: Electric tongue Jack blows fuses

You have to allow the motor to stop before reversing. It's like going from drive to reverse in a car. Nothing good happens if you don't allow everything to stop. yup. same thing on my atwood jack, my smaller barker ball screw and my barker 3500 ball screw and on my max air fan. basic analysis of electric motor principles of operation will show a much larger than normal current draw with motor running in the reverse direction when voltage is applied.

RE: Lithium crossing the acceptance threshold…

recently on my small trailer the 6vGC2 trojans gave up the ghost after 12 years. 250AH cells usually discharged to around 30%SOC dozens of times/year. Going down the checklist of a Li vs. flooded lead acid Li won the contest until it came to cost. $350 for another set of GC2's vs way more for Li along with the need for a different charger. My big trailer with 4 GC2's (10 years along) will be needing new batteries in the next few years. I suspect cost will lead me to GC2 flooded cells, but once they are done I suspect the switch to Li will win on every count including cost.

RE: How many folks want an EV

The all use CVTs which only last about 100k miles, then $5k to replace. WRONG WRONG WRONG. Yes some hybrids, and even gas only vehicles use CVT's, but there are MANY MANY MANY hybrids that do NOT have a CVT, and virtually all pure EV's use direct drive. And I know many people with vehicles with CVTs that have gone well beyond 100K with no problems. In fact none have had problems with the CVT. Now personally I don't like the characteristics of a CVT, but that's another issue. My hybrid uses a 7 speed wet clutch DCT, fantastic transmission, especially when coupled to an electric motor in front of it. GET your facts straight and don't spread misinformation.

RE: How many folks want an EV

Have a hybrid now, get's same mpg in town as highway, extra cost was $1500 and pays for itself in a few years for gas, Better performance than the all gas version, Next vehicle will likely be a plug in hybrid. That was our first choice but the one we wanted in 2020 had just been introduced and non with the options we wanted available. The 40 mile range would have been more than we need 95% of the time. If DW was still working with a 30 mile commute a plug in EV would be the only thing we'd consider for our around town vehicle.

RE: Antennae or booster

I successfully set up wifi calling. Let's see how this works now. Added: Wifi Calling seems to be working fine. Apparently, this also saves mobile battery since wifi access requires lower transmit signal level since the local wifi access point is near. yup. the lower your cell phone signal level is the more transmit power your phone needs, the shorter the battery life. So wifi calling with a stronger signal is a win. One downside is if you move out of wifi range call gets dropped if the phone can't switch to a cell tower.

RE: Antennae or booster

We also have poor unusable cell service in our park but excellent wifi. For phoning, just download skype or What's App to your mobile phone. You can then do skype-to-skype calls (free) or skype-to-phone calls (low minute-based fee). I like What's App the best since its connections are encrypted and you can call for free any phone that also has the What's App installed on their mobile. Using wifi, you can stream TV from the Internet or from services like amazon or Netflix. or simpler just enable wifi calling from your phone.

RE: Dino juice v Electrons....

discussion of EV vehicles reminds me of the discussions about the first diesel trucks non turbo and how they would never be accepted by the masses, only good for economy. Now, the energy density of hydrocarbon liquid fuel is a tough one to match either on a volume or weight standpoint. But I suspect that at some point in the not to distant future EV pickups for towing will become practical. As for charging, already for cars they are down to 15 minutes for 250-300 miles instead of overnight. yes there are lots of infrastucture issues, charging issues, energy density issues to overcome. I suspect the current crop of EV pickups will do well with local construction companies etc. that put on 100 or less miles/day around town. When we see UPS EV local delivery trucks we will be a long way towards practical EV MD trucks.

RE: Motor vehicle laws. Complicated jurisdiction question.

Window tint enforcement can change as you drive thru a city, let alone a state. Stopped because plate was not displayed like LEO expected? In another thread that can't happen. Other issue found after that stop? Another impossibility. Now you are talking about something more important than window tint. Does any state actually require insurance? Think they really want proof of a minimum level financial responsibility. From what you have posted, you did not show that. In my state that can lead to arrest on the spot. yes many state DO require insurance. The minimum amount of liability varies but states do require proof of insurance, even if your home state doesn't. A quick check says NH and Virgina are the only states that don't require liability insurance. Oregon requires you provide proof of insurance in order to register or re register your motor vehicle.

RE: Simple and inexpensive roof vent modification (Vent Covers)

any source for the brackets with the clips? I did a search and couldn't find any. I have them on one trailer but not the other.

RE: Simple and inexpensive roof vent modification (Vent Covers)

at one time the MaxAir had a clip system so you could pull pins on one side, flip the cover up, clean up the inside of dust, bugs etc. Made a nice system. However I haven't seen that available on current covers.

RE: Motor vehicle laws. Complicated jurisdiction question.

I doubt the inspection sticker would ever be an issue. there are lots of states that don't require any inspection. There are some things that aren't covered by reciprocity. a) things attached to the front windshield even if it by suction cups are illegal in some states and reciprocity doesn't apply AFAIK. b) I think window tinting may be another one. c) double towing, reciprocity doesn't apply d) overall vehicle length reciprocity doesn't apply

RE: Chirping alarms

Our rig has been in storage for the past year and when I went to prep it for an upcoming trip, I heard the infamous smoke-alarm chirping coming from it. Figuring the batteries were dead, I pulled the batteries from the smoke alarm and the Co2 detector and replaced them all with new ones (fully charged verified). But the chirping continues! What is causing this to happen? Is it fuse related or shore-power related (it's been plugged in to keep a trickle on the batteries when not being used)? We've never had this problem come up before. When chirping has happened in the past we just put in new batteries and it would stop. How old are the detectors? Ones built in the last 10 years or so will chirp continually once the replacement time hits. They don't have an infinite life and to keep people from using them for decades and decades they now chirp continually when replacement is needed.
