My trailer is *mostly* what I want. It is a 1997 Logan Coach "Ranger". I got it used last year. It weighs 2800lbs & tows great behind the 1/2 ton truck I had at the time.
*Step up (never worry about uneven ground, etc)
*Slant load (extra space & when I open the door, I can see their HEAD, not their... uh... yeah. Lol)
*Full walk in tack room with 4 saddle racks (the door locks too & has a sliding window
*Light color (white) helps deflect heat & doesn't look like a big dark scary hole that will eat my babies
*angled front, so it cuts through the wind better than a flat faced trailer
*It's tall. Taller than the trailer I used to borrow! Lol
*very large inside. With the divider open, I can haul 3 horses (15hh, 14.2hh & 14hh)
*Light in the horse area & one in the tack room
What I wish was different:
*Mine is a 2 horse. I want a 3 or 4 (I own 3 horses)
*Want drop down windows, or at least windows that open/close. (gets wet inside when it rains)
I love that it does NOT have mangers. I remember as a kid, my mom's 15hh paint got her leg stuck in the manger of our older 2 horse straight load. The horse used to "be pretty" by curling her leg when she wanted a treat... and somehow she got her leg UP above her chest into the feeder.
It really depends. For a long time I had a monstreous TB that I hauled all the time. He was an RCMP horse that was retired and he was just shy of 17hh and BIG. We had bought him a staight haul 7+ tall trailer with lots of padding, removable devider, vents and a ramp. It was a beautiful trailer, but it was also HUGE, and because it was straight haul, the weight in the trailer was really not distributed evenly because he always had to be loaded on the left side.
My first concern is always the height of the trailer. Everything else you can adjust to, but the height can be a big issue if your horse is of modest size.
