The Gray Wolf 26DBH is a bunkhouse, so I image you have kids... Once you add-up their bikes, scooters, camping chairs, etc. you will definitely surpass your TV's 1350 payload... However, if you proceed with this purchase, definitely make sure your tires are up to the task & have the dealer install a good, yet affordable, Equalizer 4 WDH, etc. If you pack very light & stay close to home, you could get the family hooked on camping before you talk your DW into the need for a larger TV...
The Gray Wolf's stick & tin design makes it heavier than pricier TT's with nearly the same floor plan, like the Prime Time Tracer AIRs. (Our dual slide PT Tracer 3150 only weighs 6,400 empty...) Some dealers will allow you to apply your deposit to another TT & a few will even refund your deposit. Choosing a lighter, but more pricey TT with nearly the same floor plan may be a better option than having to upgrade your TV in 1-2 years...
If/when you do upgrade your TV, you don't have to buy new. I found a 2 year-old Ram 2500 CC ST (stock) for $14K. I added a like-new fiberglass cap found on CL for $500 & I'm quiet happy. It has a payload of 3,000. The newer engine/tranny combo provides better mpg than older trucks. I get 17 mpg commuting & 8-10 towing... Our (used) PT Tracer 3150 was only $20K & IMO much better quality than new TT's in the same price-range & we've had 2 years w/out problems (not caused by me breaking something...)
