I agree woith all the previous posters, I have a kwik kamp that has been all over Western Canada and Western USA, towed behind a GL1800 Gold Wing with ABS, I DO NOT PLAN on pulling it behind NT. Possibly at a later date maybe a Uingo or a light weight Bushtec at the most.
IF I were even to consider that length of item behind me I would want the axle place very near the rear end of the trailer. That is based on 25 years of pulling Semi trailers in various configurations of 45 t0 53 foot single trailers, Doubles two 20 to 27 foot trailers , and Rocky Mountain doubles a 40 ft and a 20 ft behind the 40. with the length of trailer, or the Kayack setting on a trailer with the trailer axel setting in the center of tghe loaded item, you will be having a very dangerous situation in that when you make a turn the back end will be subject to swinging way wide and possily hitting another vehicle, object etc with the wheels at the back end of trailer you eliminate the previous problem, but you will have to make a much wider swing to allow making it safley arround a corner. Neither is a real safe situation to be puting yourselfe into.The weight factor mentioned should not be a problem for the NT, BUT getting a hitch set up would be a problem as no one thus far has been marketing one to my knowledge.
Please be safe and careful with your project if you decide to attempt it.
