Last year I bought my first trailer, a used
Featherlite 3H gooseneck; the dressingroom has about a 4.5' short
wall. Have had a bunch of improvements done to it so far -- battery box
with two marine batteries, exterior lighting, extension to the forward
divider so that I can use the first stall for
storage, dressingroom/gooseneck ceiling insulated, etc.
One thing that I haven't done yet, because it's
going to cost a lot, is a pass-through door from the dressingroom to the horse
compartment. Every time I camp with my horse I wish I had it.
Especially with such a small dressingroom, I wish I could spread out and put my
chemical toilet, dirty clothes bin, etc. back in the horse compartment.
With any size dressingroom, it would be great to use the back of the trailer as
a mudroom, leaving messy boots and wet outerwear back there.
A MaxxAir will be added above the gooseneck this
winter, and then the pass-through door is next.
