RE: Outside Speakers

Jensen is about as low end as you can get for speakers. Just about anything would be an improvement. I would get anything rated as a marine speaker from Alpine, Kicker, JBL, or Infinity. If you want something really high end the best marine speakers are made by JL Audio and Wet Sounds but expect to pay a lot of money for them.

RE: Group 27 deep cycle battery + 2000W inverter

Most residential refrigerators that I have measured use about 1.5 kWh per day. If you only drain the group 27 battery to 50% you'll have about .6 kWh to work with. So, my best estimate is that it will run it for about half a day before it needs recharging.

RE: Cab over Camper shell?

You might try a fiberglass body from Fleetwest. They are meant for work trucks but would probably work for a truck camper. https://www.fleetwest.net/product_type/fiberglass-bodies/ Sorry, I don't know how to make it a clicky.

RE: Calling on Solar Techies

All the "kits" I've seen are generally over priced with sub par quality components. I would try to use "full size" 60 cell solar panels which are about 40" wide by 66" long. They are about 300 to 350 watts each and should cost around $.60 per watt. Magnum or Outback would be my first choices for inverter/charger. I wouldn't mess with stand alone inverter, get an inverter/charger which will also have a built in transfer switch. It makes the wiring much easier. Some will say that now you have a common failure point which is true but these devices are incredibly reliable. Purse sine wave for sure. Buying a modified sine inverter is like buying a black and white TV. Running electric heat in an RV with solar panel is just an exercise in futility. Forget about it.

RE: Onan 7500 generator wont start in cold

What generator? Have you read the manual? If it's an Onan I think you do hold the stop for a few seconds to warm up the glow plugs. However, even without preheating it should still crank. The no cranking when cold sounds like a dead battery. Was your heater also blowing on the generator starting battery?

RE: Towing Advice

It could be that the new trailer does not have enough tongue weight. Less likely but still possible is too much tongue weight. Have you actually weighed it? Dry and brochure weights are meaningless, you need to go to a truck scale. If your dry weight is 7,800 you are likely pushing 9,000 fully loaded. If your tongue weight percentage stays the same that will be nearly 1,200 pounds on the tongue leaving you with only about 500 pounds for passengers and whatever else you put in the truck. You may need more air in your tires on both the truck and possible the trailer; have you checked the air pressure? Do you now have more weight in the cab or bed of the truck then you did before? More people, loaded tool box, generator, firewood, etc?

RE: Heart Interface converter/inverter/charger

How old are your batteries? Have you checked the water in them? If they really are dropping to 10 volts you may have bad batteries.

RE: How much weight could be eliminated?

If I eliminated half of what you suggest I can guarantee my wife would no longer go camping with me. That would have a weight savings of . . . I'd better not say.

RE: Towing capacity vs max cargo weight rating

The legal definition of overweight is either tires/axles or registered weight. GVWR is not a legal definition; neither is "payload". If you're truck's RAWR is 7,000 and the scaled weight on that axle is 7,000 or less you are not legally over weight. Even if your overall truck is over it's GVWR. However, if your total truck weight is, say, 12,000 pounds but your truck is only registered for 10,000 pounds then you are legally overweight. Again, GVWR has nothing to do with it. As to the fairly low payload of the truck in question, they are assuming a 150 pound passenger in every seat according to the text posted. So if the truck has 6 seat-belt positions and it's just the driver in there you can add 5 x 150 pounds to that "payload" rating. There are LOTS of kinds of traielrs; by far the most difficult to tow is a hard wall RV type of trailer. Boat, flatbed, utility, dump, etc. are all far easier to tow and generally have a lower percentage of pin/tongue weight if loaded correctly.

RE: Truck camper trade-in at dealer question.

I'd start by using NADA to determine a basic value of the camper. Used RVs are still extremely scarce and thus the prices are still elevated. You should be getting good money for a new one whether you sell it yourself or trade it in. Most of the lots I look at have very low used inventory and the prices are inflated over what they were a year ago.

RE: Built-in Genset on 2021 F-150

GM offered this with their hybrid Silverado back about 15 years ago. It never really caught on then. I'm in the construction industry where everybody has a truck and I only knew 1 guy that had one. I don't know how long it's been since I saw one on the road. Maybe Ford is just marketing it better.

RE: Electrical mystery--set out to fix 2 problems but fixed 3

That means your ground is floating which is common with portable generators. Thus, no tester will give you a proper indication of whether or not the outlet is wired properly.

RE: Looking for Truck + Truck Camper, Seeking Guidance

Skip the 2500, get a 3500. If you're just carrying the TC then a gas engine would be best. I'm most educated on GM trucks so I'll give you that run down. I'm sure others can tell you about Ram and Ford. A Chevy 3500 SRW comes with s 11.5" AAM rear axle; it doesn't matter if it's gas or diesel, it gets the same axle. A Chevy 2500 gas truck only gets a 10.5" AAM rear axle. If you get a Chevy 2500 diesel then it will have the 11.5" axle. Chevy 3500 trucks also come with wheels that are 1/2" wider than 2500 trucks. This is because they are equipped with larger tires than 2500 trucks.

RE: Batteries in parallel and series

OP, the diagram you have is correct. The next diagram that Old Biscuit posted is exactly the same. #2 and #4 of The diagrams that pianotuna linked too are also effectively the same. The only "better" way is a buss bar (#3 that pianotuna linked to.) For most uses you will never see any difference between using bus bar and the diagram you originally posted.

RE: Electrical mystery--set out to fix 2 problems but fixed 3

You're way too deep into electrical to not be using a meter. Those 3 light testers are handy for quick checks but will often confuse things as you have discovered. Get a proper volt meter and check for voltage you have: Hot - neutral, hot-ground, neutral-ground. Did you ever plug in any of these 3 light testers before when running on generator? If not then you don't know if it's any different now or not.

RE: does a detached over-the-air television antenna help?

A directional will beat an omni every time. Also, an antenna on the roof should beat one on the ground every time due to higher elevation.

RE: Truck Camper Security

Are you aware of what happened in Nashville on Christmas Day? And your plan is to park your camper randomly on city streets and have it set up so that alarms and sirens go off if people get near it? Sounds like a recipe for disaster to me. I would expect to be turned in to the cops at every stop. I think you would be well advised to park in a campground. Long term rates in the winter are likely quite reasonable and you will save a ton of money by heating with grid electricity instead of burning thru propane like crazy.

RE: Fridge

I can't imagine you have two Rv type absorption refrigerators; I've never seen an RV that did. Is one of them a small "dorm" refrigerator in the outdoor kitchen? Those are typically electric only and much simpler and cheaper than a 2 way or 3 way absorption refrigerator typically installed inside. Which refrigerator is not working?

RE: Questions About People's Knowledge Of Various Issues

Some people go camping, they set up in the forest or at a campground for a week and "enjoy nature" or hike or whatever. If this is what you like to do a trailer may work fine and be less expensive. My family travels via RV, we visit museums, historic sites, relatives, etc. while traveling around the country. We rarely spend more than 1 or 2 nights in the same place. For us a motorhome makes more sense. It allows for snacks, bathroom breaks, naps, etc. to all take place while in motion. (Except for the driver of course.) Thus, since selling my TC a few years ago, I'm looking for a MH. I'm looking for a class C for a few reasons: I want a driver's door, I want the overhead bunk as we have 3 children and don't want to be converting the dinette to a bed every night, and I do my own vehicle maintenance and a C strikes me as being easier to work on. I'm a Chevy guy and have had excellent service out of them. I've had a truck with the 8.1 and Allison and it was great. In fact, all of my GM trucks, gas or diesel, have given me fantastic service. However, if I had to have a Ford engine it would be the V10; no, they weren't perfect but they were pretty solid with a nice flat torque curve.

RE: Reg cab long bed vs extended cab long bed?

I carried my 4000 pound 11' Fleetwood on an '07 Chevy 3500 SRW reg cab for a couple years. I had no problems but it really wasn't enough truck; I was right at the limit of my rear tire capacity. I carried about 4,300 on the front axle and 6,800 on the rear axle. As mentioned the radio antenna hit the bottom of the cab-over part. I wrapped the end of the antenna with white electrical tape so it didn't mark up the fiberglass and just let it touch. It's kind of hard to see a stop light if you're the first vehicle in line but that's not really that big a deal. Also, Chevy narrowed their tailgate opening with the 2007.5 body change. I had to load my camper hard against the passenger side wheel well to get it to fit thru the tailgate opening. After 3 years I put this same camper on a 2005 Chevy crew cab dually. It has way less bounce and sway on that truck. I attribute that to the dual rear wheels more than the longer wheelbase. It just didn't feel as top heavy or "tippy" on the dually.
