I don't know what year your Tacoma is, but the neighbor's farm has a lot of those Tacomas. All with the 2.7L engine, manual transmission, extended cab, rear wheel drive. The manual is not great for towing- the first gear is too high. But, even with that, they'll tow 3500 pounds- I've done it before. The key isn't the weight as much as the height- wind resistance is what makes tall trailers so hard to pull. If you're not hauling small stuff much, you can make this not so bad by using stake bed sides- the air passing between the boards makes a LOT of difference.

Horse trailers can be great or terrible- I own one from the days that we raised hogs. Ours pulls HARD. If you can, you want to test-pull it first, and that's true for any used trailer. If you can't, you can fix some of the hard pulling with things like bearings and alignments. But, with any 30 year old trailer, your mileage WILL vary. Some were just better cared for than others.



But, 3500 pounds- if your Tacoma is like the neighbors' 2011 ones, you'll be fine. You'll be in the slow lane, but you'll tow better than the F-150 I make do with
