My buddy bought a Javier van about 4 years years ago. As he was deciding what to buy, the shiny Javier van seemed like a good deal. 2003 4WD 7.3 Diesel E350 with a 6" lift on 37's.
The attached picture is his Javier van and my Vanagon right after he bought it.
Most immediate problem was a dry transfer case upon delivery. Lots of little things. One of the seat belts was two seat belt ends with the webbing spliced together using 1/4-20 bolts. It had mismatched door locks. No two doors unlocked with the same key. I don't remember all the issues he addressed but it was many.
Overall it was a high mileage van with lots of wear, poorly done modifications, but a shiny paint job. EVERYTHING done, including that paint, really needed to be redone.
It scared him so much towing a trailer he immediately shipped it to Ujoint Offroad to have them put their leaf spring/axle kit on it. Currently he has replaced everything Javier installed except the front bumper and the paint, and the paint is discolored and cracking now so it will be soon.
He would have spent far less money buying a stock low mileage van and having Ujoint do it in the first place.
