Peterbilt 379 daycab to sleeper conevrsion

If you have enough wheelbase it is possible. I have never done that just took them off. Is it cost effective? Probably better to buy a different truck.
Well lets thank out of the box and back up a few years. Clarence had a 4000 White butterfly hood with an add on dungeon sleeper, 24 inches I thank. It probably would not have been so bad but he had not cut out the cab to match the sleeper opening. It was near the fuel island and I heard an odd sound and asked about it. No that's just Clearance. He is hung up here for the weekend and just walked back from the bar, feel through the window into the dungeon, he will be fine.
Joe told me he saw a F model Mack day cab sleeper at a fuel stop in OK. When he came in the cab was up and the guy was wrenching on it. He said the sleeper was made out of plywood, square box mounted on the frame but the paint matched. Let the cab down, put a large tire tube between the cab and sleeper, inflated it and drove away.
Just food for thought but I would go with plan A, buy up.

 

Will it be a uniblilt? How big of a sleeper do you want to add? The Pete cabs all look the same, but the internal structure isn't the same between a day cab and a unibilt sleeper cab. The windshield frame which Pete calls the mask is aluminum in a day cab, but steel in a unibilt cab. The brace over the doors that goes down to the floor is a lot stronger in the unibilt cab as well to support the weight of the sleeper. You might get by with adding a 36" bunk since they're not as heavy.

 

I was at the steam show in Mt. Pleasant Iowa 9 years ago and saw a pickup slide in on a Freightliner classic if I recall correctly. Any thing is possible

 

The unibilt comes in two can models. Ultra cab and flat top. The unltra cab is taller and the sleeper hole is taller. If the truck was once a sleeper and made a daycab than the job won't be that bad. If it's factory day cab don't thinks it's worth the time and money to do the job.

 

It can be done. Knew a guy once that turned a short hood day cab into a long hood flat top. Moved the cab back 8" I believe to make the long hood work. He also had left the factory day cab air ride on to help support the added weight of the 63" sleeper.

 

On the upside nice day cabs always fetch good coin. You may come out with a similar sleeper truck with a little cash left over.

 

Bump.

Anyone else running a day cab Peter with a unibilt 36"?
