Do you guys have your own camper shell now? I don't know how I missed that.
Hey, Dzzz. You must be thinking of someone else. My boss and a couple of the other guys here starting building composite bodies for beach buses ad campers over 20 years ago and has been doing it ever since. Probably have molds for well over a dozen different types of "shells" lying around.
I'm looking at using hydraulics for leveling jacks on a U 500. It could be useful for vehicle extraction, but maybe just make a big mess. I plan to use cross supports between two hydraulic cylinders that operate independently.
This seems to me the best way to control stability.
You vehicle is closer to the ground and may be inherently more stable.
In '03 I had to fit a "folding/levelling leg" system that we adapted from a Kwikee RV kit. Once we extended the legs to cater for the higher ground clearance of an FG on XML tyres, it worked quite well to aid recovery in sand anyway. Of course it was really handy to be able to level everything when you arrived at a campsite.So anyway maybe the controller part of the Kwikee RV kit (and maybe even the pump and valve bank too) could be useful for your setup. It also had reed switches on all 4 rams so if you had a hose failure and a leg started to drop a warning comes up on the panel. Also the control panel was setup for exactly the purpose of levelling. So you could operate legs individually or in pairs of legs. So say you could lift up the leftside only but with one button. Very easy to use. Then it had an "all up" button.
This was the pump that came in the kit. The one in the middle with the 8 hoses going to the manifold on the end of the pump. The pump at the top of the pic and the other remote valve banks were for the winches and spare wheel / trailbike lift.
And as I just put this pic in to show that it doesn't really hang down at all to cause a problem.
And with the legs down. Although I don't know why.
Oh and definitely brace between the rams on your U500. Good move. When they lift really high, you're right, I think it could get very unstable.
I'm not sure what you mean with the charging system. I believe a properly regulated large alternator can do a much better job at charging house batteries than most people believe. I hate diesel gen sets.
As you know good marine alternators do a great job with house batteries.
Well actually a properly set up yacht will have 2 alternators. One for the start battery and a second smart (3 stage) alternator dedicated to the house batteries. The second alternator would also be programmed to charge at the correct parameters to suit the battery type( ... AGM, gel, etc.) rather than simply a single alternator charging both battery banks (and most likely different battery types) in parallel.
The system I'm talking about (and we really are only trying it out now) takes power from the start battery,solar, and 240V AC if available and provides true 3 stage charging to the house bank. Sounds good in theory anyway. Certainly a neat install in basically one main box with a remote LCD display / control panel rather than a mains charger AND a dual battery system AND a solar regulator AND a battery management monitor.
A normal alternator is not really designed to charge deep cycle batteries efficiently either. They take a long time to reach that "float" point that a smart unit will get to in the optimum time.
