Miles_Sisu,
We can run rough numbers and draw some conclusions…
- Tundra Payload: 1450lbs
- 2 Occupants: 360
- Luggage: 50
- Vehicle Mods & Accessories: 150
- Additional Gear Allowance: 100
* Remaining Payload / Tongue Weight Allowance: 790lbs
- XR22 dry weight: 5200
- Tongue weight: 425
- Propane & 80lbs of batteries = 500 tongue
- Fresh Water, 30 gals: 250lbs (~15% transferred to truck = 535 tongue)
- Food & Beer: 30
- Luggage & Furnishings: 150
- Additional Gear & Toy Allowance: 500!
*Total Trailer Weight: 6650lbs
*Total Tongue Weight at 10%: 650lbs
*Remaining Truck Payload: 140lbs
The math indicates that even with the lowest available towing capacity of 8800lbs you can load up that trailer with
a lot of cargo and still be below all the maximum rated capacities.
Its my opinion that factory rated capacities represent the maximum
prescribed capacities as agreed upon between the engineering, legal & marketing departments. There is an
enormous safety margin built into these truck's ratings and as a platform they’re capable of safely and reliably performing well above their published ratings.
For example: just adding springs to an otherwise stock truck in Australia can increase payload by 20-30%, as certified by federally licensed engineers. Further anecdotal evidence supporting my claim are all of the fully built and laden rigs featured here and other websites that are grossly overloaded yet travel great distances with superb track records for reliability and road safety, albiet with suspension & tires upgraded to match the mission.
This is to say that loading a Tundra up to it’s maximum factory rating isn’t “cutting it close” in any practical sense what-so-ever assuming your load distribution, hitch, ride height, trailer brakes and driving habits are all configured appropriately.
What the truck
can do, what it
should do and what it's rated to do are very much subject to your perspective on math, insurance liability, fuel economy, passing power and "peace of mind". As per Toyota’s R&D the 5.7L Tundra is plenty. But is it future proof for you?
