Hi Clinton,
"Couldn't get it level on some carpet's?"
Which carpet's?
I've been using mine for the last 3 1/2 years from new. Never been a problem. Yes (as mentioned by Richard) early day's it left a 'line' a couple of times, but that was more about my not using it properly.
Just curious, if you no longer use your R/V is it for sale?
Adi
