2015 or 2016 Tacoma

Looking for a small truck to pull a trailer 4600 lb. loaded, 330 dry tongue weight 24' long. Tacoma specs seem OK at 6500 lb towing capacity and 650 tongue weight with towing package. Also I need on demand 4wd. Does it have enough power? Is the 127 " wheelbase long enough?

The V6 2015 Taco is rated at around 3,500 tow capacity unless you get the double cab which is 6,500lb or something like that. The 236hp these trucks come with isn't exactly hefty so I would really reconsider using a tacoma to begin with. Hate to say it, but you would be better off with an EcoBoost F-150 or comparable Silverado/Ram 1500. I'd at least go with the 4.7 Tundra, but if you're talking full size trucks the Tundra is easily worst in class.

To answer your question: on paper the tacoma can do it, but it would be a bit of a struggle.

What kind of towing? My 04 tacoma has a 5000lb tow rating and honestly it feels like it struggles at high elevations on steep grades towing just a 1600 lb trailer.

If you're just towing flat then yes a gen 2 is fine. Might struggle in the steeps but a gen 3 probably will also. At least with the gen 2 you get that proven 4.0.
