The great= your Dog
The Good= your trailer
Ready for the bad news ? these are fine trailers, dont get me wrong, but i personnaly know a guy that had the same trailer,do not leave your dog in that trailer for more than a week at any given time, there is something about the moisture and the construction that expell gases that attack billit aluminum, no shit iv seen it.
Keep a 60 watt light bulb going in that trailer when your not useing it. it will keep things dryed out .
