I just bought a 20 foot trialer that has split tailgates almost 6 foot high. Anyway, each one honestly weighs a TON and Im a big strong guy. Ive searched and searched but all the ones ive seen attach to the top of the metal sides but mine doesnt have any sides and I dont want them as I load my quads from the side. Well I was planning on using garage door springs and attach them to each side but Im afraid that the trailer side of the spring would be too low when the gate was down and wouldnt help any. Do you guys agree? Any ideas?
