I'm currently looking to buy a 2 horse, slant, bumper pull trailer and would love any advice or experiences on the handful I've narrowed it down to thus far. It will be used for relatively local travel primarily during the spring and summer, but I do live in the northern Midwest so there is a possibility it could be exposed to salted roads at some point. The 3 I'm currently most interested in, all of which are priced within $1,000 of each other, are:1) Used 2012 Featherlite 9409 (all aluminum, sold as-is)2) Used 2009 Kiefer Evolution (steel frame, aluminum skin, wood floor, with some noticeable rust already visible when looking around the wheel area)3) New 2014 Bison 720 (all aluminum with 6 year structural & 2 year hitch to bumper warranty))Any insight, experiences, opinions, etc would be much appreciated! Thanks!
