I have a Tacoma and a two horse trailer and trailer locally on the regular. I’ve also gone from Atlanta to Lexington (one big horse on the way home) and done travel around the metro Atlanta area for several years now with my little rig. Rig specs are: '06 Tacoma Pre-Runner 2WD, short bed, double cab and ugly, red '93 bumper pull Carry-On two horse slant (Atlanta folks, say hi if you see me out!).
Tiny truck, tiny trailer.
My experience has been this:
I don’t particularly want to travel on the highway for long distances. The stability of the smaller truck is not the best when you’re getting passed by semis and other large vehicles. I’ve done it, don’t get me wrong, but those are the times when you realize your truck is pretty under-sized (and yes, I know it is).
The trailer brakes make the difference in braking, for me. I would not, under any circumstances, tow that trailer without the brakes with my truck - but I’m a little nutty about wanting to be able to stop.
Local hauling (1-2 hours tops) is fine. Anything that isn’t a several lane highway seems like no problem at all. I don’t worry about anything unless I expect to be passing/passed by a lot of large vehicles.
You’re not going to accelerate fast. It’s a Tacoma towing near its limit. Thems the breaks.
I have relatively small horses and haul two of them no problem in this trailer (14.2h and 15.2h). The big guy is 16h and long. He actually doesn’t even fit in my divider. Hauling him is fine as long as it’s just him. Since he’s divider-less, I haven’t hauled him and anyone else yet. My other two horses are likely in the 1000# range each. Again, hauling both isn’t that big of a deal.
The bottom line is that it’s do-able. A light trailer is super helpful. The Tacoma is awesomely versatile (mine has almost 200k on it and hasn’t had ANY major issues). Sans trailer, it’s a comfortable daily driver and can park just about anywhere a car can. I’d trade up to a full size or 2500# if I could afford it, but I can’t. So long as you’re going with the newer, bigger body Taco, I think you’d be alright. But don’t expect to be the nicest looking rig anywhere you go
