Can you tell me the size of the sleeper?

Looks like a 60" to me.

 

I was thinking 48" to 60". You can tell by the upper sleeper window. 70" have a split window.

 

You are right, that is Intl's 51" hi-rise sleeper. It is tight in there, but at least you have a shorter wheelbase to get into those tight spots.

 

I haven't been in one of Intl's small sleepers, but in the one volvo 42" sleeper, the front seats basically butted up to the bunk. In that cornbinder (and in FL's) there should be a little more room. Maybe Wally92 can comment, since Wallyworld runs a lot of Intl's with that sleeper.

Here are some pics off Intl's website, they are of an Eagle trim (the highest trim level) interior, so your truck may not have all the features this one does.

 

These are the same size sleepers that Anheuser Busch uses for transporting the Clydesdales. They were exactly as pictured in Wallbanger's post. I never had to sleep in the truck, as we were always in hotels and never traveled over night with the horses in the trailers.

If you get the Eagle trim package with Monson then you'll have some room, but don't be surprised if you find a bare bones sleeper. Most large fleets won't opt for the high end trim packages on their trucks. I have seen guys with 40 qt. electric coolers on the passenger seat in smaller trucks like these.

 

Yeah Scarecrow, that Eagle package is nice looking! At least the WalMart drivers are riding in style!
