I really want to continue this discussion John...
My trailer has always been a pain in the ever loving butt... I move the car
all the way forward in it and get the CG of the car Well forward of the
trailer axles and then jack up on the load leveling bars and it still
creates massive amounts of Vacuum....( yes it still sways and su......) I
also have a Generator and the air compressor and cabinets forward of the
axles as well as 4' of trailer extra on the front....
So tell me folks what IS the answer?
