Finally had a chance to test out how my '14 Tacoma DCLB tows my 21' Tige Wakeboard Boat. Thought I'd post some pics for all those curious about the towing capabilities with a 21' boat. Tacoma did great and will do the job for me all summer long. Glad I don't have to trade in my new truck for a new Tundra(even though I love those trucks).
My Taco has a 3" lift with AAL in the rear. Sags a little bit and I will add air bags soon. I have a 4" adjustable ball mount and have set it for a 3" drop(due to a bit of sag), but will probably set it at a 4" drop when I get the air bags installed. This is what I originally had it set to when I measured everything, but didn't take into account the sag. Trailer now sits level with the 3" drop. So far, so good.
I originally phoned my dealer and was inquiring about a Tundra, my sales guy told me "Why? That Tacoma was built for towing those things". Told him all my specs and weight and said "it should be no problem, and that boats are more aerodynamic than TT's are when towing". He could have easy told me otherwise and sold me a Tundra right on the spot but he didn't. He said he's been towing a 21' boat for years with the same truck. Glad to know and hear his stories.
Boat dry weight is 3700lbs.
Trailer is approx. 1000lbs.
