The 'super duty' 1720lbs max load trailer is on sale with coupon for $349 til 5/31. From what I've read pretty comparable to the past when they still accepted 20% coupons on the trailers. I picked one up couple days ago after weighing my decision between the 'heavy duty' 1190lbs load and the 'SD' 1720lbs and found most people were saying the same thing about the smoothness of the 5lug wheels, ultimately my 'but what if' hormone got the best of me and I ponied up the extra $90 (HD $259 vs SD $349) I decided on the 1720lbs load. I like the idea of being able to fold it up and hopefully tarp it with a ping pong table cover I got lying around. Just started the assembly today, hope to wrap it up tmw and get it registered. (My assistants were not so assisting) Instructions are lacking but the illustrations are better detailed.
