Most people don't need to tow a boat, and those that do only need to do so a minority of the time.
People should have the option to bike to where they need to. Instead everything is basically designed around cars being the only valid form of transportation.
When our species develops a philosophy without the need for accumulation of wealth, a inflatable kayak will do and can be easily transported by biclycle.
You don't need a truck to tow a boat either, especially not a big one. Probably nearly any motor vehicle could tow the majority of boats that are being towed, not that most people who own a truck are toeing boats and not that boats are being towed often anyway. Just rent something the one day a year you take the boat out if you need to. It'll save you money in the end.
The VQ40DE engine they put in the 2005-2019 models is a great engine. The RE5R05A transmission is solid as well. If you get one make sure it's either past 2008 I think or the radiator has been replaced. The stock radiators had a flaw where it would make strawberry milk by mixing your coolant and transmission fluid usually around 100k miles.
The Gen 3 tundras have the coolant to trans fluid heat exchanger on the right side of the tranny where the thermostat for the tranny fluid is located. Keep that in Mind.
