lookin at buyin a ford 95 f250 single cab long box and throwing the flatdeck from my 85 chevy towtruck on it , the frame is a bit to short and im just wondering about lengthening it , i know its possible , thinkin of some channel iron and then some 1/2 plate to fishplate it to the origional frame bolted and welded , my deck tilts so the back of the frame has to be structurally strong because that is where the hing point is anyone ever done something like this before? :confused:

with our wreckers when they get lengthened, we cut the frame and put in another piece, and then double the frame with another piece of C-channel inside the original frame. :dontknow:

That's a good point, what's the GVWR of the 250?

Please tell me you don't use c channel. That's just wrong.

I wouldn't start with a f250. The frame is thinner than the 350, the front is much weaker, and if you do up your gvw, and you can, if you get into a crash icbc will be saying fuck you cause ford says you can't do what your doing. Not to mention that to deck a car on a set of singles is just asking for cvsc to pop you.

As far as actually doing it, sorry, but I say don't. If you want the 7.3, I can understand that. find yourself a old u-haul truck and swap cab and motor.

I've lengthened my old f350 regular cab and added 22" for it to become an extended cab. Did a inner formed "C" that was 48" long as well as a filler piece to fill the void. I used 50w material for both. The frame was prepped internally, welded, then gouged out externally, and welded at all 4 joints with the 48" piece bolted in place. I regularly loaded 3-4 tons on it and never had a problem.

I'm building a deck truck that is based on a buss. I know there are haters, but I still believe this is an awesome way to go. If you can find an international one, not hard, and find yourself a international cab, again, not hard to find, you can build yourself one pretty cheaply.

I'm building a chev right now that I tried to section and stretch the frame, but was running into non stop problems, so I basically axed the entire frame except for the front suspension. The new frame is fully boxed and working out very well. Might get some pix for you if I get back there tonight.

Ya i have a 1 ton chevy right now with the deck on it , its a 85 rilly old and needs alot of work plus im not a chevy guy , i have so many ford parts i could build 5 trucks there what i know, im gettin sick of havin no power goin up hills and having to tighten up the bolts between the tranny and bellhousing on the 4 speed , i understand where your comming from on the 350 frame id like to get one if someone would sell one for a decent buck , my buddy has a 92 f250 with a 460 and a 5 speed 4x4 , it would be getting a propane/gas dual fule set up as well as a 60 up front and a dually 10.25 in the rear and the leaf pack out of the chev if i end up doing it

i would love to build a bigger truck but for what i do i dont think its cost effective , between the incurance , MVI's and repair costs , if it was my full time job i would go with something bigger but its just a weekend thing for now

im still trying to find a f350 , but i found the f250 its in good shape and has low k thats why i was leaning towards getting it :confused: :dontknow:
