I have a older Astro steel tandem wheel trailer with metal fenders . The only reason i would consider doing this is the a 1850 dxl is in pristine condition . The trailer isn't in terrible shape but the boat out shines it so id like to dress it up . I know where there is a set of tandem wheel fiber glass Ranger trail fenders that are the colors that match my boat . My question is this change out do able and have any of you done such a thing . Just how hard would it be to do ect . Your opinions are wanted . Thanks
