Even though we have a less than 3 month old unit, we see the carpet showing a lot of wear. Especially on the steps, where the slides rest when in, and the vanity area. Has anyone replaced the factory carpet with a better and thicker grade of carpet? I'm curious of the tolerances regarding the slides and if we installed a better carpet, would we have a problem with clearances? We've had great carpet in the past, and there's not much under these, so this will wear very quickly. The staples that were used are also very sharp when you step on one barefooted.
