Funny ryansgirl, because I have about the opposite feelings. I will never get another ramp, seen too many injuries on ramps, and every horse I’ve had has hauled better in a slant. I’ve had a few broodmares who absolutely refuse to load in straight loads.
There is a lot of research out there on what horses prefer - and most prefer to ride BACKWARDS, or backwards at an angle. So - unless you have the $$$ to get a custom backwards trailer (yes, they can be ordered that way), then you have to consider next option. Research shows more horses prefer slant then straightload, BUT - there is strong preferences with different horses, so you need to ask your horse :lol:
As for used - not an issue at all. Have the floor checked, have the wiring checked, look at the tires. Do a careful check inside and out - any rusted spots, any sharp edges to be worried about? Trailers hold their value well - it isn’t like buying a used car - you may find that a 10 or 15 year old trailer is only 25% less then a new trailer. But that 25% might make the difference between affording the trailer you want.
Personally, I won’t ever own a trailer with an aluminum floor. IF it needs repairs, it is a lot of money, and they never retain the same strength. AND - I’m in a hot climate, and aluminum conducts heat - my horses don’t need to stand on a hot floor - rubber mats can help, but it is still a hot surface. There is a reason they use aluminum for so many cooking pans.
As for aluminum vs steel shell - there are arguments for both. I started out longing for aluminum, but after doing some research and consulting my budget, I decided to go with steel. It is a bit cooler, and it is a lot less expensive. For a 2 horse trailer, weight wasn’t a huge issue (I have a Ford F250, no problem pulling).
I didn’t want gooseneck - it eats up the truck bed - for a 2 horse it didn’t make sense. If you are going to camp w/ your horse, or stay at shows a lot, then it might make sense - but to be honest, the extra cost of the gooseneck pays for a heck of a lot of hotel bills! So I went bumper pull. Easier to hook up and unhook, and leaves me a truck bed to fill with hay, muck carts, etc when I’m going for a while.
I went and looked at a lot of new trailers in my price range (which was limiting the quality of the trailers I could look at), and finally looked at used trailers. My requirements:
2 horse slant
2nd stall had to be big enough for a good sized horse (some slants have skimpy 2nd stalls)
7 feet tall (or taller)
Dividers needed bars so horse wasn’t feeling to confined
No ramp
Wood floors
Well lined with rubber inside (safety and helps protect trailer against pawers)
Wide open entrance - no tack room at the entry, and no “dropped” edge at the top of the entry (some trailers are 7 feet tall, and the entry into the trailer is 6.5 - WHY?).
Open on the butt side (like a stock trailer - I’m in a hot climate and want that airflow).
Drop down windows with bars on the head side
Sealed tack room
Since steel - double lined body
I kissed a lot of toads, and inspected a lot of floors. BTW - floor repair is not a huge expense for wood, so don’t panic over a bad board - just use it as a bargaining tool. Ultimately, I found a used trailer (about 11 years old) at a dealer - brand new tires, they replaced 2 floor boards for me, added a bit more interior matting and clip so I could tie back the divider and use it as a box stall, and they put a new plug on my truck since my old trailer used a different plug.
You need to consider your tow vehicle and your budget. Go look at some trailers - look at things that you like and don’t like. Ask the trainers who have trailered your horse - does he have any trailering issues and/or preferences?
