Thanks for the advice and sorry for the delay in responding- was at a horse show all weekend.
Arelle, RAyers, BEARCAT- The +1 would be used for my tack. I hate the small triangular spaces created by slants. A 6x8 foot box seems like it would be SO much easier to organize and keep neat that 2 triangles. I keep 80% of my tack in the trailer at all times, so big space is important. I also want a roof hay rack.
There would be a full divider between the two horses and the box. My horses all get along extremely well, so I’m not concerned about them kicking or biting each other. They have head contact in my current two horse straight load and they are great. That would be a consideration for future horses or if I ever have to resell it.
cutter99- Thanks, that was what I was afraid of.
Guilherme- I know the 6x8 is a bit small for a stall and the loose box isn’t ideal, but again, it would only be in an emergency when I need to evacuate all three horses, so I’m ok with it.
I included the slide because I was trying to minimize length while maximizing space. TBH I’m scared of ending up with a trailer that’s so long I hate driving it. I was already counting on it being a pretty heavy trailer, but it sounds like I would need to make it a 10ft LQ to have the slide, so that may not be an option anyway.
IPEsq- I would not be using the rear for a box stall ever.
CLB15- Good idea about adding an escape door in the 2-horse part!
Bluey - Thanks for the reminder about the wheel wells… that was a major oversight on my part and I’m not sure where exactly to draw them in. Also, good point about which side the front ramp goes on- I hadn’t really thought about which side is better.
China Doll- Thanks for the budget info. My design crams it all into 24 floor feet, but that might have to increase in a couple places. Yes, gonna add a foot of length to the 2 horse stalls.
SimpleSimon and Puddin Pie- Making the stalls 7 feet is a good idea and maybe adding .5 ft head space. It’s supposed to be 8 feet interior width, but leaving out the wheel wells was a big oversight on my part. I’ll need to figure out placement of those…
crosscreeksh- Good point about which side the front ramp goes on- I hadn’t really thought about which side is better!
