Kayak on the back of a Travel Trailer (?)

Kayaks are light weight , no pictures ! I made two things that kinda looked like square basket ball hoops and clamped them on the back bumper . the sides of the hoops were made width wise so that the yaks sat into the hoop several inches , one yak on each side of the spare tire . I installed stainless boat cleats on back of trailer outboard of loaded yak .For securing in the center above the spare tire , another cleat on my first trailer , on the second trailer I placed a metal upright from the spare tire mount up to the height of the outboard cleats . What is important to me is to keep them in close for less leverage/weight .
