Congrats OP on the new ride and new trailer! With our 5er, I'm 54.5' nose to tail and just south of 22k and very little problems towing. Also have a 4 place V-nose alum snowmobile trailer and nose to tail is around same length as w/ the 5er and total weight w/ 3 sleds is approx between 13-14k (never scaled out). Sled trailer is NOT on WD hitch and it is very noticeable when pulling it. Was much worse when old sled trailer was steel frame. Point is, the 5ers do tow much nicer and tho my sled trailer isn't all that bad towing, anything heavier (trailer weight above 5k), I'd have a WD hitch on it.
