378 Day Cab Conversion.

Factory daycab? Sure it could be done but would be a lot of work. I'm sure the back of cab would have to be cut out to add in ring for sleeper boot. Might be missing some other bracing too. Not to mention sleeper to cab brackets not there. Also if you want a stand up bunk you'd have to get a non ultra cab opening. Heat would be easy to plumb but ac would take some work and cost. Probably really not worth it unless it had a bunk at one time.

Least that's my guess to the problems

 

Can be done but do you honestly really want to? There's enough Peterbilts out there with sleepers already on them. Probably the easiest and cheapest solution.

 

Would honestly like to know what’s involved myself. I’m in the middle of purchasing an old 1990 international 8200 day cab I wanted to put a sleeper on.

 

Any info on how to go about it or a pointer in the right direction would be much appreciated

Throw a 36 or 44" on it and you shouldn't have issues. The 379 I ran with a 36" was literally a daycab with an opening behind the seats. Put some little airbags under the bunk and you'd be good to go

 

The best way to do that if you're really serious about it is that when you buy the sleeper you need to be able to go to the junkyard and see the truck while it's still together.

Then look at how that sleeper is actually mounted to the frame and how it's mounted to the truck and take everything from the donor truck. If the sleeper itself has air ride you have to see the way that it attaches to the cab and the way all of that works together.

I don't know for a fact but the truck that has the back of the cab cut out from the factory may have additional bracing in the roof or floor or back of cab or whatever to make it stronger and compensate for that.

 

Thanks y’all for the information I appreciate it
