That trailer is a giant and heavy PIG...nice trailer for sure but you'll be WAY......WAY over your GVWR. Only real safe way to pull it is with a 550 or Freightliner......we have several friends that have learned the hard way....that those trailers are a lot heavier than you think and WW is notorious for underrating the weight.
If it were my family I wouldn't even try it because I think it would be unsafe....plus there's the legalities....I think GM only lists that truck's Maximum trailering weight with a 5th wheel at 16,000 lbs....and a GCWR of 22,000lbs...truck probably weighs close to 6,500lbs wet....so that only gives you 15,500 lbs left and that trailer probably weighs that much empty........if you were to get into an accident you could be in trouble.
Don't get me wrong I love the new WW trailers just need to make sure you have the right tow vehicle.....It's not worth risking the family in my opinion.
