Well I looked at it and here's the good and bad:
Good:
Belts, hoses, brake lines are in good condition
Engine starts right up (faster than my 2010 Outback), doesn't make any funny noises or smoke under throttle, oil isn't black or metallic, none in the coolant, ATF is red and not burned.
Much of the interior is in very good shape. Fridge, AC, Stove, lights work.
Tires have tread and aren't sun damaged/cracked
Suspension, steering, and frame bits all seem to be quite solid. Rusty, but not structurally.
Brakes are good and not squishy.
Bad:
Tires are 7 years old
No idea if the tank monitors work or water heater/sinks/drains since there was no water hookup
One side wall is definitely water damaged. 3 feet of it is soft in the cabinets (the laminate isn't as flat as I should be and flexes more than the other side) and there's a little bit of softness halfway down the wall
No dash AC
Rear table is wobbly, seems like it needs a new pole
I wouldn't trust the ladder with my weight. The wall seems pretty solid, but the ladder itself flexes on the mounts.
From a ladder outside, it looks like the roof bows down slightly in the middle
How bad is the wall? If the leak is stopped, or could be stopped, would it be fine since it's aluminum or should I just run immediately? Suppose I got incredibly lucky with the guy, and he'd take $5k for it - would that be a decent deal?
Regardless of whether I run from this specific one, I'm pretty darn convinced on the Toyhome idea. Visiting it in person let me realize that it's pretty much perfect for my needs. Does anyone know of models other than the Sunland Express have the same layout as this one? I *really* like the 3-sided table-bed in the back of this thing, and the compact shower.
