Help with tow rating for 2011 Toyota tundra and new TT

Hello, we are looking at a 2015 heartland prowler 26p bhs. We have a 2011 Toyota tundra and we are confused if the GVWR of the double cab tundra will be overweight? Here are the numbers:

2011 Toyota tundra double cab 5.7 liter 4x4
GVWR 7100 lbs
Approx weight of truck is 6000 lbs
Towing capacity is 9300 lbs

2015 heartland prowler 26p bhs
Dry weight is 6246 lbs
GVWR 9000 lbs
Hitch weight is 760 lbs

We are concerned that the hitch weight is taking away from the GVWR of the tundra and will only allow for approx. 340 lbs in the tow vehicle (including persons in the vehicle). Are we doing our math right or should we look at other numbers? Thanks, we are so confused, we are used to towing a 1988 popup and want to graduate to TT towing! Thanks in advance.

  • Thank you, that's what we thought but pretty soon the number crunching gets a lil fuzzy. We originally wanted to go with a stick and tin but now we are looking at a north trail 28brs, much lighter at 5180 dry and has everything we need. Thanks so much for the input!
  • Keep the trailer weight to 7k or less and you will be much happier. Make sure you have L T tires on your truck. My trailer wouldn't be more than 6,500 lbs. and tows quite well with my Tundra.
  • Your concerns are valid. If your calculations on the truck are correct, you have 1100 lbs payload to work with.
    -----------------------------------------------------------------------------

    If you subtract the actual truck weight from it's GVWR, the remainder is your payload.

    From your payload you need to subtract loaded tongue weight, 100 lbs for the weight distributing hitch, the weight of your occupants, and the weight of any cargo in the truck.

    With 6246 dry weight, the trailer will weigh (average load of dishes, pots and pans, camping gear, BBQ, tools, groceries, water, and bedding, etc, is 800 - 1000 lbs) 7000 - 7300 lbs loaded. Average tongue (hitch) weight is about 12.5 percent of loaded trailer weight. That would give you tongue weight between 875 and 912 lbs. The 340 lbs, you are concerned with, will more likely be under 100.
  • That's not a good combination, IMO. We towed a TT for 6 years that weighed approximately 7000-7500 lbs loaded, and though the truck pulled it well, I always felt the tail was just a bit bigger than the dog would like. We downsized last year to a TT with a GVWR about the same as your trailer's "dry" weight and it's going much better.

    Good luck with the decision.
  • Yes, you will be over your GVWR, with that trailer. Your loaded hitch weight will be close to 900 lbs. You also have to figure the WDH, will be almost another 100 lbs.

    If you don't load the truck will firewood, gear, etc., you will likely get by, just like many others.

    If everyone towing over their GVWR stayed home, there would be much more room in the CGs.
