Measurments
John,
First things first, I've got a couple pictures, but I'll need to post them later. Also, there is good and bad in here, so read everything!
Next, all my info is from my '08 ATC SuperDuty Panther. I'll stress the SD as I understand that ATC builds them a bout 2" taller for the higher cab on our trucks.
The door is 46"x28", but the couch takes up some room, making it more like 46"x18". I'm 5'11" and have no problems getting in or out. (I use the "ladder" as a hand-hold when exiting.) This door is, in my opinion, the make or break for you: if this entry is too small, you will need something else.
The height of my camper closed is 53.5". The bed slide is 6.5" and it extends into the camper about 34" or so when the slide is extended. The height of my camper popped open is 77" (6'5"). Don't be disouraged yet, keep reading!
I have an extended slider making my upper bed approximately 81"x81". If I were you, I'd get this "king" extension and sleep up here. Getting up could be a pain, but you could look at a
ladder.
The lower bunk unfolded is diagonally 77". The room in the aisle is 8". I do not intend to sleep here, I don't think it's real comfortable and its a pain to fold out. The FWC's have an easier to deploy couch. My opinion is that this will NOT work for you.
So, how could this work for you? First, will the door work? If you can get around that issue then there is hope.
Make sure you get the extended slider, they might even make it longer...?
Second the pop-up on Eagles and Finches is taller, and so a Panther or Hawk could be too, I'm sure, bring the camper height to one you could stand in. Talk to both Ben and Stan.
Third, you could put the Couger/Grandby size camper on you truck and have the couch built out another 18" or so for a lower bunk you could sleep on.
ATC's website has some great inside pics under floor plans. Check both the
Cougar and
Panther. The cougar has some dimensions on some pictures.
Also, the Panther is about 4" wider than a Hawk, I understand.
Finally, if you can afford it, I think you should consider the SportsMobile 4x4 Vans. Money no object, I'd have one.
