    Hey guys I bought an 1999 F550 6 speed manual with a 16 foot box last year to replace my fallen Fuso. It was an awesome deal, but it has 250k and long wheelbase. I put an L pack on and the dump body from my old Fuso. The body didn't quite fit because the Mitsubishi had a narrower frame. So, it's been sitting for months!!! On the other hand I bought a cab chassis 2004 F350 with 6.0 317k and with one injector, wiper problems, it runs AWESOME!!!! I tried to sell the 550 with no takers as of yet. I looked into chopping the frame down and putting on a 10 foot dump or something but chopping would be about 2k, and with a dump my investment would go up a bit. I know folks are partial to the 7.3 but which truck would you keep realistically? It pains me to see the 550 just sit there. The 6.0's horror stories make me want to put the 7.3 in a time capsule for judgement day.:dizzy:

    Id take the 7.3 550 It will be heavier duty and is designed for exactly what you plan to do.

    I'd keep both. Find a used dump body that will fit the 550 and put it on the road. Since both trucks are high miles, it'll be nice to have a back-up if the other has to sit in the shop for a while.

    Scrap the 6.0. Sell your dump body. Build or find a new dump for the 7.3

    I sold my 7.3 with 365k on it and it still ran perfect

    Put a cheap flatbed on the 550 and sell it all put together. The 6.0 won't bring enough to justify selling while the 7.3 will sell at a premium if it doesn't look like a project truck. Or keep both - the 550 has a great chassis, engine, and trans. Also get an aftermarket oil cooler at the very least as preventative maintenance on the 350. A high mileage 6.0 is sometimes on the second or third motor so it could be younger than the odometer suggests. Get that oil cooler replaced asap unless it's already been done. You want an air to oil - not water to oil setup. EGR delete too if you can.

    I appreciate the the advice. I just have to cut down the frame on the 550 to fit a 10 ft body. Right now it fits an L pack and a 12 foot body, entirely too long. My 350 is all put together and we used it all last year. I'll post some pics
