Very solid, easy to put together (instructions say 1hr, could do it blind in an hour) works great for factory doors, the hang on the door pegs and there is a small L bracket that the doors fit behind to keep them from opening while on the rack; not so much for the ADD doors, they will need to be secured with some bungees and moving blankets…only thing would be better is if they used the wasted space in the middle to somehow store the roof panels ( may try to rig something up)
