Our son-in-law recently purchased the family farm from his dad. Among the old equipment he got are 4 1/2 (4 complete, one for parts) Deuce and a half 6x6 trucks. Two 1954 M220's, one M211 (year?), one 1966 Kaiser Jeep M35A2, plus the parts truck, another M211.
He's asked me to get them running for him this summer. Once I do, he'll decide whether to use them on the farm or sell them and put the $$ towards other needed equip.
Three of these trucks have old potato beds on them. The M35A2 has a flatbed. His dad and grandfather used them years ago. They haven't run in 15 - 20 years or more. From what I can tell, they were all converted by Boyce Equipment in Utah.
The M220's (one engine free, one engine stuck) still have the GMC straight 6 engines. Automatic transmissions have been removed and replaced by Clark V205 5 speeds. M211 has a small block chevy w/ 5 speed. M35A2 (multifuel) appears all stock and all there. Haven't spent much time on it yet.
Here's some pics. I've also started three different threads on Steel Soldiers. Been getting lots of good help from the guys there. I'll put the links to those threads after the pics for those who are interested.

Pulling Boyce #1 out of the cellar after 10-15 years. Son-in-law and granddaughter in the 4630. Got this truck running the other day.

M220 #1. This one's just about ready to fire up. Still need to clean out the gas tank.

M220 #2. Engine frozen. Put ATF and PB Blaster in cylinders. Check it each week.

M35A2. This one is still in the trees. It's next in line after I get M220 #1 running.
