Looking at the profile of this James Baroud on my trailer, it's pretty slim...and this is their largest tent. ..they have smaller ones that don't allow for cargo to be stored on top, which makes them even slimmer (and lighter)...I'm thinking if it extends over the cab by two feet, your overall height would be the same as a folding soft tent centered on the bed...and you will be moving the weight more forward over the middle of the truck...
If you want, I can take some pics today of the inside. It comes standard with a 2" foam mattress, a solar powered ceiling fan that can be reversed to pull air out to prevent condensation, and a Velcro mounted ceiling light that is 12v rechargeable...
