all you need is a power and ground wire to repower, like an xb terminal for a wench or something like that. that way you can still get power to your battery in the case they go completely dead.
Depends on if it was stored inside or outside. If inside id just check fuel pressure or make sure you have fuel pressure and fire it up. If stored outside you will at the very least make sure there is no water in the fuel system.
I just used the cheap stuff on mine, im sure it will hold up for years to come. Once the oil gets soaked in to the boards there as good or better than pressure treated :redneck:
There's also some cheaper solutions on the lift like using rears up front and some good ol chev 63s in the rear. Im not sure how the trail gear springs work but I know the ones im suggesting work well IMO.
I had this same problem when I repowered my wheeler. I came across a celica with a running 22r for $300. I pulled the engine and completely resealed it, and its still going strong today. I parted the celica and made my $300 back to boot. Im currently running propane right now and im very pleased...
