I am reupholstering the valances/cutains in our trailer. Can't believe someone thought it was a good idea to decorate with all dark brown everything in a small space. Will post pictures when completed.
Here's a sample of before & after.
Dean did measure everything before he built this just to be sure that we are good. The back of our trailer is quite a bit lower than the front. This type of rack would not be good for kayaks that are longer than 10' just for the reason you mentioned.
Yes, those are extra lights. We do run a ratchet strap (not shown in this picture) from the middle vertical bar where the middle crossbar is at down to the outside corners of the rack to help stabilize it.
