Hello, I am new here and have a question. I ordered two 2u sparks and I am looking at a used all alum double trailer with a 1550lbs payload. The trailer is 91inch wide from edge of fender to edge of fender and each bunk is 25inchs wide from edge of bunk to edge of bunk. My question is will this work with my new 2015 2u sparks? The bunks stationary and dont adjust. Any advise will be great.
