I wasn't planning on it but I ended up getting a trailer!
It's not some new fancy slant load but the price was great, it's sturdy, in great condition, and has lots of room for the beast. It has a spring loaded ramp, walk through escape doors on both sides, and is padded inside. The inside is in mint condition. It's 7'4" in the low spots on the sides and 7'6" where his head will be. I know they come taller but not in my price range.
It has a few surface rust spots but this is Oregon so most steel trailers have some. The trailer lived in a hot dry climate until two years ago. There isn't a tack room which is a bummer but I looked into 20+ trailers in my budget and nothing was over 7ft. Dickie's comfort is more important than my convience.
