62" sleeper with 238" wb; top long?

If you pull flat it is what you want. Bit long for van.

 

It's fine. The truck will be a little more versatile for you.

 

That would be the prob for a van. But as mentioned if you pull anything else you might want that.

 

Headache rack, Hose rack, tool box? Some states give a little more weight depending on overall length, could end up pulling a flat etc. There's more options to trucking than just pulling a van.

 

Wouldn't say it's too long for any application. Mine is a 232" WB and that's with a 77" sleeper. My father currently runs a 260" WB, pulling dry van and reefers.

All about how your setup is when maneuvering. Unless the space you are trying to fit into is physically smaller than your combo.

 

Definitely not too long.
Even with 379 a common truck in Canada was 63" sleeper with 244" wb. An excellent setup for weight distribution and not so long a wheelbase it is difficult to drive. We are limited to 244 without permit - for another discussion.

That should be a good truck. Get bunk extenders if you want to close the gap a bit.
