So I am either renting a trailer or borrowing one to get my 67 lemans to the coast of nc, (about 3 hours away)in April. The car is stock ride height.Trailer 1 is 20 ft flat metal deck with I beleive 5 or 6 ft ramps. Trailer 2 is a 18 ft with 2 ft dovetail, 4 or 5 ft ramps, and wood deck. Which would be better for hauling the 17' pontiac. Also the 20 footer has surge brakes where as the other has electric brakes. Just want to get the one that will be better suited.
