I have a Sled Bed I bought new in 2000, no problems with the wiring, but the aluminum welds on the under side of the frame work started to crack after a year, out of warrantee of course, I have e-mailed the company and have had no response from them so my next trailer will be something other than a Sled bed, oh ya I noticed the dealer that I bought it from doesn't carry them anymore either.
