Hello, i have a 91 ford f-350 Custom Lariat 2wd AUTOMATIC dually 7.3 IDI Diesel 4 speed over drive transmission has under 160k original miles, runs great Has Dual tanks. Has new brakes all the way around and two new front tires. new alternator, batteries, fuel filter, oil change, all them parts there havnt been on the truck for more then 2000 miles, Also has a Reese 5th wheel just can slide in and out of bed very easy (is heavy tho) worked great but havnt used it in a long time so no idea but it has been always garage kept and looks almost new so im sure it is fine. The truck just sat for Quite a few years in the garage before bringing it back to life again about 4 months ago drove it to work and back everyday (about hundred miles each way) Runs great. Only thing im not sure about, it went to florida few years ago and friend took the belt off and put a smaller one on that does not go around the AC said more power because we were hauling a trailer, i havnt put a new belt on that goes over the ac so no idea but the little ac compresser is not locked up it turns freely. Also the back tires look in good shape have very very little dry rot but good tread so thats why i didnt replace those. but driving the truck it has had no problems it runs amazing. any questions or if i forgot something and you would like to know just call me 1779-200-0489 i just posted a video of it all around and the inside and it running so i hope this answers alot of questions i been getting and if not you can always still call me Witch Ebay wont let me put the link in so just look up Ford F-350 7.3 powerstroke custom lariat dually and dual tanks in your search on youtube and you should be able to find it should be first if you type exactly what i did. the name it is posted under is Tony Capuano.
