Ok so here's the skinny. If a buddy of mine sells his truck, he wants to buy his work truck and trade it to me for my truck. First off I have to ask if this is a fair trade, then what my options are for this differently (but similarly) equipped truck.
My truck:
E99 f250 7.3 psd pickup, auto, crew cab, xlt, short bed. 383k miles. less that 8000 on 285/75r16 pro comp a/t tires. Hypertech power programmer 3. DIY intake. cat delete. bad icp sensor. layover and drivers side tool boxes. 4x4. 3.73 ls differentials. stancor relay. idr if thats it but im pretty sure lol.
His work truck:
E99 f350 7.3 psd cab chassis, zf6, standard cab, 165 inch wb, xl. 70k miles, 5080 hours (i think that calc'ed out to bout 170 ish thousand miles?) Mix and match tires (looks like 2 were bought at a time) steel wheels. Stock exhaust, stock intake (checked for pass thru, all clear

) Completely mother effin stock. 2wd (damn ifs

) 3.73 non limited slip differential. Bed is about 12 foot, steel flatbed with underslung tool boxes, aluminum rails and a lift gate (think a tire truck bed, because thats what this used to be lol) pto that runs a screw compressor (he wants the compressor tho).
Ok, now the questions. Whats the major differences between the cab chassis and the pick models, minus the bed obviously? Can a stock bed and bumper be bolted on? What is a bed like that worth (the one on there)? I want to make this a dd, that I can also hook up to a gooseneck or trailer. and how come I found a reese hitch assembly that said not for cab chassis models? Is there anything I should know/ look for when considering this. This would be my first dually, cab chassis, and manual, so any pointers would be appreciated. Got the 7.3 look over down lol. Also how will the 3.73 non limited slip (i assume open?) differential fair in the snow, rain, bad weather, and wet ground? He says he only managed to break it loose once, but he had to try (wind it up, dump the clutch, and be on snow). Is this just because its a heavy s.o.b.?
Sorry for the bombardment of questions, proly hafta ask more than once because theyre all packed together lol.
Thanks in advance,
Jason
