Ryan, I just PM'd you but I'm going to throw out some more info here.
This is the rig you might want to steer clear of. Why? You can do a lot better for your budget and it's really not that great of a deal.
The solar is old, only 80 watts, and will need updating. For your proposed use at the beginning of this thread I recommend 200 watts of NEW panels. The technology is astoundingly better. Still probably a $300 DIY on the newer van you're considering.
The inverter is small, like 600 watts I think? I would recommend a 1000 at least if you're going to work out of the van, run laptop chargers and the like. The Zamp pure sine inverters on sale at Lowes right now are an amazing deal, and pure sine!
The fridge is tiny, and there's no way that old solar runs it efficiently or for long. They're exaggerating when they say 'solar powered fridge'. They mean solar powered for a little while, until the batteries drain down.
Older leaf spring suspension is going to beat you to death. Those things ride ROUGH!
5.8l in that older 4x rig is going to hurt you on fuel mileage, bad. I'm betting 10 at best, maybe less. The newer van with a 5.4 will get 14-15, maybe more. *Everyone online exaggerates fuel mileage except me.
The people who say they are getting 17-18 in a 5.4 are having illusions of grandeur. I got 12-13 with my heavily loaded 5.4 van, but it had a higher top and was an EB and much heavier build than this one. I would bet you'll get 15 in the newer 5.4 van if you don't lift it too high and put huge tires on it.
I also suspect this 91 is going to nickel and dime you to death. It's 15 full years older than the newer van you're considering. Just sayin'.
The unusual yet open floor plan of the newer van is growing on me, but that's just my opinion of course. It means nothing to your needs. You could stealth camp sleeping in that rear single bunk when needed and stretch out with the top up otherwise.
