Agree with all above posts. I worked my last 22 years for Toyota. We sold many Tundras for use as oil and gas field service trucks. Their only downfall is the low payload ratings, however they ran for years overloaded in rough use and I never saw a failure due to that. Rear axle assy is very robust, much more so than most half tons. Many put extra spring leaf or air bags on. So for a light trailer no problem. Personally we towed 2 different 10000 lb 30 ft 5th wheels with our 2011 Tundra, as we are snowbirds and had no issues. Now have F250 but only because I was uncomfortable being not legal on truck GVWR. Fuel mileage towing same 5th is similar to Tundra, however Tundra driven same way unloaded as I drive the F250 (gas 6.2) would get 3 mpg (imperial) better on highway. Enjoy your Tundra, if they had the payload I need would still be driving one.
