For the ramp lovers and for those ramp haters who are afraid of slippery ramps. The solution costs just a few bucks and lasts years. Go to your feed store and buy a bag of ground limestone aka Di-Cal. Note, this is not white lime, or slaked lime, or any of that nasty stuff. It is grey and looks like what it is, ground up rock Keep a bucket of it in your truck and you’ll always be prepared.
Sprinkle a bit on your ramp, especially if it’s raining, and you will not get any slipping. Winter trailering and have to load from an icy spot? Sprinkle ground limestone wherever your horse will or might step. The effect is immediate.
My own trailer is extra everything (big/tall) 2H straight load GN and was raised for the previous owners. That makes my ramp super steep. I have had zero (knock on wood) problems with horses not negotiating it safely. I have zero horses come off stressed.
I searched high and low for the trailer I wanted that I knew my horse would prefer. It would have been easier to buy a slant, but for a little 16 hander, she is long and picky. She will load into anything. She will travel quietly in anything. She will self-load into anything once. She will only refuse to self-load into trailers she doesn’t love - small 2H and slants. She will come off a slant or an old style 2H straight slightly frazzled despite having travelled perfectly quietly. And, although she will be led back on like a little lamb, she will not self-load. “If I have to get back in that thing, you have to get in too!” LoL
Really glad I had the opportunity to beg, borrow and cadge rides for her before I made my decision on what to buy. Super glad that all her friends seem to love it too! So, opinions, I have a lot but my actual advice would be that if at all possible, try to find what your horse likes and what you are comfortable with before you buy your trailer.
And yes to GN over BP if possible, unless you’re going to be negotiating impossibly tight yards on the regular.
And ramp over step up. I have seen some scraped shins from horses stepping out onto ground that was soft and slippery With a ramp, I am always there to keep remind them where the edge is to keep them centred and not step off sideways like hooligans. Totally personal though. Many people use step ups and will never see an off-loading accident.
Fwiw, the one horse I knew that was always hauled in a stocker always chose to ride backwards with her head on the curb/passenger side. That mare was dreadful to load in a 2H. I wonder if her opinion about loading in a 2H would be different these days with wider, taller, and brighter becoming more the norm .
