Leaking ProStar sleeper windows...

[DDB]

Forgive me for bringing up a dead thread but this came up in my search. And, also please forgive me if this is a dumb question.

I'm shopping for a truck and I've been trying to figure out if you can add an upper bunk to an International Prostar MID ROOF truck? It seems from reading this thread that at least some of them did come with this option, but I was hoping someone could confirm this for me?

For flatbedding I prefer a Mid Roof but when I was trucking before the upper bunk of my old condo came in very handy, both for training other drivers and for the occasional child (I've got four of them) that wanted to ride with Dad.

I know that the Cascadia (and I think one of the KW's) offer this option. Just wondering if the ProStar ever did? If it did then it means there should be hardware allowances built in that would allow a fairly straightforward conversion from single bunk to double.

And this would bring more possibilities into view as I shop. Thanks
