Didn't realize National did things that different. IIRC my Escaper was 11-gal Black, 12-gal gray and 22 fresh. A friends Winne was 12/12 and less than 20 so they would carry an extra 5 gallons of fresh. I guess with the Dolphins you could carry 20 gallons of "spare water". Still, have to manage water carefully, for anything longer than an overnighter. My current Winne is a lot easier for an extended stay with 40/54 waste and 84-gal fresh. Of course, the downside of such prodigious capacities is the 75-gallon fuel tank. Filling that up is a lot more painful than filling the 84-gal freshwater tank. 😢

The tanks in a Toyota RV are small. Like 12-13 gallons ea for black and gray, with 25-30 gallons of fresh. Water management is a must. If you're in an RV park don't hook up the drain hose and open the valves. Major bad JuJu. The black tank will develop the dreaded black mountain. Leave the hose hooked up but drain the tanks every 2-3 days. Drain the black tank first. After draining the tanks get a couple of gallon jugs and fill up your tanks so you can see how big they really are and see if the gauges work correctly IF you can measure your tanks use math instead of the gallon jugs, there are 231 cubic inches in a gallon.

My Escaper had a full-time rear bed. It was great for 2 people 1 up top and 1in the bed. Think of a hotel room on wheels. It was great if you were outside all day, just fall into bed. On a rainout day, it was too small for 2 people.

There is a drip tray under the finned condenser inside the refer It should have a drain tube to the outside. Check to see if it's plugged up.

NFPA 1192. 5.1.6.3 " Valves Access Door and Panels. Doors or Panels providing access to valves shall not be equipped with locks or require tools to open" That law enough??☠️

FWIW You can not lock the propane compartment. Clamps or straps for holding the tank are easy...https://www.pplmotorhomes.com/parts/electrical-plumbing-lp-gas/lp-gas-parts-1/bottle-racks

Well after all this trouble and the fact that it's a 4x4. You need to head back to the wrecking yard and find a dash mounted Toyota Inclinometer

Boring math... A typical small 4 CF RV fridge uses about 850 BTU per hour. There 91,000 btu's in a gallon of propane so a gallon of propane is worth about 120 hours in average temps. A 100-degree temp will bring usage to 1400 btu or 3 days per gallon. A honda1000 will run the same refer about 8 hr per gallon of gas +ware and tear on the engine.

Your transmission has 2 safety start switches. Neutral and Park. Looks like the park switch has gone south. Well now you can at least get MIL home 😃

Mountain driving. #1 Basic rule go down the hill in the same gear you used to up the hill. Check brake temps a few times at the bottom to get a feel for things. If you can't keep your hand on your middle of the rim, you're going to fast.

A 4Runner cluster will run $200, a Small tach will run $30. Heres an example... https://www.ebay.com/itm/Bosch-FST-7906-Sport-II-Tachometer-2-5-8-New-in-Package/264294550990?hash=item3d892ecdce:g:NggAAOSwx5hbw7j2. To make your engine really happy you need to change the rear axle ratio. Common upgrades are to 4.56 or4.88. $450-$650 eBay

What kind of tools do you have access to?? A 20-ton press and adapters are needed. SO choices here are, buy new A-arms with bushings installed (easy peasy way) or pay a shop to replace the bushings. Full blown poor country boy redneck approach. Get a propane torch and burn out the old rubber, then use a cold chisel, hacksaw, Sawzall to split the metal sleeve and then pound it out. Installing the new one, a press is really helpful. BUT you can use a BIG vice and a cheater pipe on the handle. A chunk of pipe big enough for the bushing to slide into. Press in one bushing, insert the cross arm. Grease the other sleeve, make a C-bushing out the pipe by cutting a slit down the side. This will let you support the arm and use the vice to squeeze things together. Full blown flintstone is to rest the arm on the vice and use a BFH to drive in the bushing. Replacing bushings is a 2 person job

On a lot of Toys with small generator doors, the unit was installed from the bottom. The door was just to check vitals. Maybe an oil change. For major work, you dropped the generator out.

There is no pressure on the return line...unless the PO misaligned the T when it was installed and peeled off a chunk of rubber hose and that is blocking part of the return line. The ONAN has an electric fuel pump is it OFF when going down the road? Weird stuff. Remove the fuel line from the ONAN carb stick it in a bottle and have someone start the Truck engine and see what comes out. if you get fuel, remove the Toys gas cap and see what happens. A correctly working tank venting system will have a vacuum in it when the truck is running (the hissing when you loosen the gas cap). If it is building pressure that's not good.

My Escaper genset ran fine with the T in the return line. There is no pressure on that line. The return line goes into the tank to the 3/4 level. The main FI line in a major nono. I'm unsure about the evap line, but I think it goes into just the top of the tank so the genset wouldn't run long if it was there. Jackup the RV and see if you can see if any clamp is leaking. USE JACK STANDS

Duct tape and a tie wrap.

A stock or almost 22R doesn't need a whizbang oil pump. Buy an OE quality one. Aisin is a reputable company, avoid the $25 ebay ones. If you just gotta have the whizbang one get a 22RET turbo pump. Beware there are a lot of 22R pumps being sold as 22RET pumps. The turbo pump has a different gear pitch and has a higher volume to support the turbo oil flow.

If it's removable just keep it someplace safe and install it when you go on a trip. Druggies use propane tanks to transport anhydrous ammonia. That stuff is very corrosive stuff so they need replacement tanks often. They have also been known to go to big box stores and buy exchange tanks, release all the propane and use the empty tank for their trade. Then exchange the damaged tank for a fresh one. If you use exchange tanks look carefully for green corrosion around the valve

The Pulse-Tech comes in 12,24,36,48v models. The only thing the unit cares about is the voltage. So the 12v unit will work with 2 6v batteries in series (my setup) or with 2 or 3 12v batteries in parallel. If you have some spare time between fishing trips, take a stroll through their web site... https://www.pulsetech.net/ .

Choices.. buy a solar controller that has 3-4 stages. Some mfg call their controller a 3 stage others that do the same thing call theirs a 4 stage. What your looking for is an equalization charge stage. A desulfator as a bit different. This is what I use for a desulfator... https://www.ebay.com/itm/PulseTech-PowerPulse-12-Volt-Battery-Maintenance-System-PP-12-L/183658489068?epid=2254333963&hash=item2ac2e624ec:g:bVYAAOSwaEdcTyhv. It'snn powered from the battery so there is a small constant drain. The solar panel will handle it though.

Boat repair ships will do HD upholstery or n=know who does. If you want water/kid proof stuff this is where you get it

I don't know if this is compatible with the primer you used. https://interlux.com/en/us/boat-paint/topcoat-finish I have used it to brush paint an RV door that was fuzzy fiberglass, Thinned and 3 coats of brushed on paint made a hard shiny finish. No idea about metal.

Kevin.. Before you spend any $$ go here and read the entire sticky...http://toyotamotorhome.org/forums/index.php?/topic/4321-brakes-load-sensing-proportional-valve-lspv-and-lspbv/ A simple adjustment can greatly increase the effectiveness of your brakes. 90% of older Toy MH's need rear spring bushings. On the scale of things, they are a VERY cost effective improvement in ride quality and handling. Before you spend $$ on making things "better" you need to make things "right". Right often includes shocks, rear springs/airbags, front brake pads and rear brake shoes. Its important check for rear seal failure and grease soaked brake shoes. There is a long thread here about front bushings..http://toyotamotorhome.org/forums/index.php?/topic/11352-upper-control-arm-bushing-removal-replacement/.

On your Renogy chart, I don't see any adjustable parameters. It appears to just be a status report. Normally the adjustments are battery type- Lead, Gel, AGM, and if the load function is in use or bypassed. There are special controllers for LiPo batteries.
