Wonderful trailer. Says that it can be put together in 2-4 hours, it took me 5 1/2 hours in 91 degree heat, 85% humidity. Instructions were straight forward and well put together.
One Note: prior to installing or before your first long trip with the trailer take the tires/rims to your favorite tire shop and get them balanced. I didn't and the trailer and 2 kayaks lightly bounced all the way to the water and back.
I Highly recommend this trailer, sturdily built... and with both kayaks mounted the tongue weight was still less than 50 pounds.
The Malone Downeaster Micro Sport Kayak Trailer has easy to follow instructions. Quality is good. Customer service is excellent.
