I went from a 3horse slant goose Merhow to a 2+1 goose 4Star and also initially questioned if I really needed that much trailer. It really is an awesome trailer and extremely versatile.
Pros:
I was eventing at the time and while I mostly just trailer one horse at the time, when going to a horse show, there is all this extra storage room for hay, feed, a scooter, muck bucket and feed buckets, additional tack trunk, wheel barrow, etc. and you don’t have to worry about it raining and getting wet. I got extra bridle and saddle hooks and just keep all the tack I use in there on a regular basis so I never have to worry about if I have something with me. Easy to take my daughter and her horse as well when she was still showing.
I’ve gone to a lesson with an indoor with it pouring down rain and tacked up my horse inside the trailer and then led him down the side ramp into our lesson. I ordered mine so the divider gates between the straight stalls and the +1 area butterfly either way, so to move a horse in the straight stall forward, all I do is fold back the gates, pull the center post and walk him forward and tack up.
It’s a great trailer to trailer into a show with without having to rent a stall. It opens up well with good ventilation and you can loaf in the +1 area or set up a picnic table, camp chairs whatever. I’ve even bought mosquito netting, a curtain rod and hangers where I could camp out of the +1 area if I wished. Some get marine batteries and fans installed so they have an independent power source to run fans.
We trailered our Polaris Ranger side-by-side home from TN in it.
Have also hauled llamas and minis and a Mustang horse that had not been tied in a trailer before, in the +1 area.
I helped a girlfriend move her 2 horses and a donkey all in one go instead of her having to make two trips with her 2 horse bumper pull.
Also took a friend and her horse along with mine up to SC to stay at a stables and go riding on the beach and we packed all the gear needed into my tack room and +1 area, again without the need to use the bed of the truck and therefore did not have to worry about inclement weather.
Cons:
You will need a 3/4 ton truck
It is a pain to get in and out of gas stations and you have to be selective where you put the thing
The 4Stars are very well made; Adam also makes a good one for less money; Shadows are nice for their price points.
I upgraded my axles; added extra lights; butterflied the interior gates; got WERM flooring; added extra saddle racks and bridle hooks with carpeting behind; a clothes bar, a step to the dressing room and sprung for the quiet ride. All very worth it.
Now that I am not actively showing, I honestly have contemplated if I might be better served getting a 2 horse bumper pull with side-ramp but I would lose a ton of storage space and they just don’t tow as well. Also contemplated maybe getting one with small living quarters since it’s just me, but most of those are slants and my big horses simply won’t fit on them, so the 2+1 is a good compromise, because, as I said, I can use the +1 area to set up a cot and table and my mosquito netting shears and quite comfortably primitive camp. That or just go to places which offer lodging for now. My younger horses are smaller so it may be that one day I do go that route.
