What is the biggest RTT that fits a DCSB?

I am looking for a larger size RTT like a 3+ from CVT or Tepui. I am 6'2" and 200lbs, my girlfriend, and two 7 year old kids. Figured I would get one with the full annex like the extended rainier from cvt or the Autana from tepui. The specs are very tight and was wondering if these would fit without much if any overhang? Bed rack would be the Brute force fab rack that is the full length of the bed.

 

I’ve seen people doing 2 and 3 person tents all the time. But one thing to remember is the bigger the tent, the lower you want to keep it. That particular rack may be really strong, but it doesn’t look as beefy as others I have seen.

 

I just put a Mt. Ranier on mine. Sits on an all-pro rack (stay away from all-pro, they suck after they get your money). It's nice rack, but damn they slow. My tent only hangs over about 12 inches off the back, which is about equal to the rear bumper.

 

Would love some side pics if anyone has them.
