Burn_e,
I am glad things are fairly calm for you and that you are able to take some of the work inside and get out of the weather.
Thats an interesting problem with the air compressor. I would be interested to find out where you finally do mount your air compressor so it stays cool in the kind of heat you get out there.
I just put some 12v outlets into my Rover today, hopefully some of the info I post will might help with some ideas for your Rover.
As for the ticking noise, does it tick once for every one rotation of the wheels?
Would I do the long range fuel tank again...hmm...now that a bit of time has passed between me and all that labor it took to finish the install. Even though I didn't really enjoy the install, it was due more to the short time frame I put myself into then it was the actual labor involved. I know what I would be getting myself into now, and I know the things to do, and things not to do. Not to mention, I really hated having to fill up every 220 miles. It is really nice to have just passed 400 mile and still be going on only one tank of gas. I can honestly say, I would probably do it again (just not anytime soon).
Sill tanks are not a bad option as long as they don't hang low enough to get punctured by rocks. My first choice would be the type of tank I just installed, the second choice if (I couldn't do the style tank I have now) would be sill tanks.
I really don't like the idea of carrying too many jerry cans, because there are jerry cans for both fuel and water. Every extra can of fuel is one less can of water I cannot carry. With the 32 gallon LRFT I have now and one jerry can of fuel, I will have a pretty good range (470-500 miles) between fill ups. That means I will be able to carry 2 or even 3 jerry cans of water.
The stock tank I had could at most, only fit 19 gallons of usable fuel, meaning I would need to find a place to store another 2 or 3 cans of fuel to equal what I have now. That is a lot of jerry cans to be carrying around and store, especially when the water cans are added in too.
Plus, if someone is not careful when they fill up with a jerry can, they can accidentally start a fire if they don't ground the can on a lug nut first. Jerry cans can build up static electricity from the moving around that happens while driving.
