I DIY installed a Bigfoot manual push button system on our previous motorhome in 2008, and the job went without a hitch with everything supplied fitting perfectly and working correctly. Any questions I had were answered promptly either by email or phone call as appropriate. I even received a phone call on a Sunday from an inquiry that I didn't expect to be answered until Monday. I couldn't have been more pleased with everything. I was also pleased when we were looking at our current motorhome, that it had a factory installed Bigfoot automatic system that has also worked well with minimal maintenance. Another leveler brand wouldn't have been a deal killer, but the Bigfoot system was a definite plus.
