We just recently purchased a Edge M21. We just got back from a camping trip that lasted about 10 days and covered about 600kms. I've never pulled a travel trailer before, but have owned both an overhead camper and a motorhome. One thing I noticed was that my pull vehicle, (in this case a KIA Borrago), wants to jerk (for lack of a better term) side to side while towing, especially when being passed by larger vehicles or in a wind... it almost feels the same as when you ride a fast boat down a river, as the current changes the boat has a tendency to want to follow the current, thus a sharp side to side movement, (for those who have experienced it). I don't know if this is normal or if it is a problem with my hitch or something. Otherwise the vehicle seems to be large enough and powerful enough to pull this trailer. Isn't this trailer streamlined to cut through the wind easy? Getting passed today by a semi almost put me into a concrete barrier...Help?
