My 3h is…I think 18-19 ft on the floor. 7 wide, 7’6" tall. I have a Ram 2500. GN deck is…7-8ft.
I don’t find this size a problem. But, size was a factor. I saw a 4h for sale that I was torn about but, the overall length was going to start being a PITA skipping in and out of crowded parking lots, tight places, and peoples homes not intended for rigs, that I visit sans horses.
Biggest thing is…make yourself practice backing in around stuff, moving it in tight quarters.
I hauled a racehorse stud around for a friend—in and out of racetracks with really jammed up parking and everyone has a GN of some size. It also gave me a good idea of what size is big but u can still snake it in easy with some practice…and what really is big enough it starts being a hassle unless you really need one that big for that many horses.
*** also, for those thinking dressing up the dressing room on a 2h w some perks may be a good options—check out youtube for stuff on airstream, van and bus living, tiny house, rving. You can find many good ideas, simple stuff, products, solutions. Trailer shopping you see some god awful DIY LQ’s that are IMO a real turn off. You can definitely make yourself a comfortable DR to camp in without getting into huge sums of $$$$ or hassle.
Also-- when negotiating price with a dealer, even if it’s used trailer—try getting them to add in stuff if you can’t beat down there price anymore. For the dealer, things like adding a 30amp shore power, a water storage tank, a ramp, a walkthru, a roof fan, interior fans…this stuff doesn’t actually cost them much. Theres a huge mark up on it if you pay after the fact…but the actual labor and parts don’t cost them much…so you can fenagle these add ons to increase value of your final price.
In terms of toilets/WC. Most campgrounds that you’d want to stay in—have decent showers/WC. I have a camping compost toilet I learned about from Tiny House folks. Its a 5gal bucket with seat, kitchen garbage bag, and compressed sawdust pellets like “woody pet” I get mine at TSC. It’s so simplistic. It absolutely doesn’t get smelly. Really. I didn’t believe it either! You just put some wood pellets in bottom, and sprinkle more ontop every time you use it. When ready to throw out, tie up the bag, throw in dumpster. I know it sounds!!! But it’s very effective, not gross, not smelly at all. If I am at a campground I use it when I don’t feel like going down to WC, or driving…no more ??? rest area bathrooms. I like it aalso because it “dry” . If the potty gets knocked over …no gross smelly spill. I don’t have to pour anything out eeew gross. Really—it’s been the best quik camp potty solution Ive ever tried. Cat box for, er, ahem, people.
For showering–there’s a lot of options. Solar shower bag can work great–showering in the horse compartment doubles as keeping it clean ;0) There are also electric water heaters—like bucket heaters, w a thermostat, stick it in your gravity feed water tank…take a warm shower. Or there are small portable propane water heaters you can hook gravity feed or hose to. Theres even some neat battery power pumps w shower head—tack a water bucket, leave in sun to warm, stick you shower head pump thing is—voila shower. And mosst nice campgrounds—that you’d actually want to stay in—have good showers. Every likes a hot shower.
