Towing with Toyota Tundra - any input or suggestions?

Keep the trailer GVWR within the tow rating and you should be fine. Forget the dry weight or expected towing weight when loaded, go by GVWR. Be sure you are looking at all options that might lower the truck tow rating. Don't expect to also load the bed with 500+ pounds of firewood motorcycles etc. Get a good anti sway hitch and go have some fun.
