LOL - I know you said your horse is a paint but are you sure there's not some appaloosa there too?
I used to think that if you had the money, you could convert a large RV into a combination RV and horse trailer. It seems the biggest problem would be the height of the floor - you'd have to overcome that or you wouldn't be able to load and unload a horse. Surely someone makes something like that.
You would think so but I've looked and haven't seen anything. If I was going to buy an RV why not a combination so you wouldn't have to pull a trailer and could actual pull a boat or small vehicle if you wanted. Just seems more efficent to me. I would think you would need very sloped railed ramps though. Would a ceiling be high enough or the floor frame strong enough if you converted an RV though?
