We have had one for several years; a three horse, 13' LQ with mid tack. It's built exceptionally well with no structural issues. It has a fully lined and insulated stall area, plank flooring system, sturdy hardware, rigid and strong doors. Ours has a complete Showtime interior, I've seen other trailers with different brands of interiors. The roof is made of a one piece double walled beam fiberglass structure. You can walk on it like a sidewalk with no flexation. If there is a situation, I'm hesitant to call it a problem, it would be with the roof. Where it connects to the sidewalls, are attached curved aluminum transition pieces. Aluminum and fiberglass have different coefficients of expansion, and if the caulking is not maintained, the roof will leak at these joints. Most any trailer with a LQ needs proper caulking maintenance, and a Sidekick is no exception. We have had no issues with it at all. In fact its excellent brakes and tracking, literally save my family's lives last year, when we jackknifed twice at 65 mph. It twice pulled our truck back upright, when the front tires had tucked under when we slid sideways, and we were on the verge of rolling over. We consider our Sidekick to be a life time investment and enjoy it more with every usage. I highly recommend this brand. If you do a search, you will find some limited threads about this make of trailer. It is not wildly sold or known about. BOL Gard |
