Surge feeling with 5th wheel?
I just towed my new 5th wheel with my 08 SR5 4X2 for the first time. It is relatively heavy, probably around 8500 lbs as towed. I installed air bags to accomodate the extra hitch weight. I have towed regular a TT before with no problems and was assured that the 5ver is a much easier tow. However, I experienced something new. A feeling the the truck was experiencing a surge from the trailer. I'm not sure how to explain. At first I thought it was the transmission shifting gears, but that proved to be not the case. It's as if the trailer is being buffeted by a regularly spaced headwind, which causes a the trailer to change its effective load on the truck. It is relatively evenly spaced phenom. Has any body had this experience, and if so, any explainations why and is there something I can do?
