I have a 2005 Ponderosa 3-horse slant load trailer, steel. It has been stored inside and there is virtually no rust. It has rear tack and large dressing room. I'd like to sell it because I am now hauling with an RV and I need to lighten the load (going to a 2-horse aluminum). I have used this trailer for 6 years and have no complaints. Pictures are available. I'm in NW lower Michigan
