I purchased the 289-SUA2000i-2 for my camper. I placed them on a carrier attached to the trailer receiver and everything worked great.....EXCEPT... while the generater were run i went into the camper and the vibrations were so bad i had to turn the generators off. do you have any suggeations.generators started on the firt pull and ran great.
