1985 F250 6.9 IDI 4X4
I've been talking with a guy about purchasing his 1985 f250 with a 6.9idi mated to a 4 speed standard 4 wheel drive and have a question. The truck in question about 160,000 miles on it and i'd say at least half of that was used to pull a fifth wheel horse trailer. is this truck going to develope transmission issues anytime soon or are they pretty stout? Could other issues arise from this. The current owner says it doesn't fall out of gear under load. Anything else i should be worried about?
The plan for the truck is a 2'' lift, 35'' tires, detroit locker for the rear and thats pretty much it. I want to build a reliable truck to drive on road trips (up to 600miles per trip) this summer out in the back country of California and not worry about being stranded 70 miles from the nearest help. Thanks for any input you all may have.

The whole cavatation issue worries me with those 7.3 motors. However, a 5 speed would be nice and the extra power, which isn't much, would be another bonus as well. No bodylift for the truck i get just suspension. I might even do a 4'' lift but i want the truck low enough to get my dirt bike in without breaking my *****.

if your gonna lift it go with a straight axle,cheaper to just find a old f350 straight axle with same gears and swap,it would give you 3-4 inch i think,i have a friend with a 86 f250 4x4 6.9 4 speed runs great,its turned up 2 flats smokes like a tar kettle will pull anything just not fast.

ATF will help power and cleans the injector tips as well......
