Adding Levelers?

I had the straight down Big Foot levelers installed on my 31' Four Winds Dutchmen (Class C) on a Ford chassis this past May. I went to Quadra Mfg. in White Pigeon, Mi since they are the ones that manufacture the levelers and I figured they would be the most knowledgeable installers. I set up an appointment with them and parked behind one of their buildings and had electricity the night before the 6:00am appointment. They started working on the installation about 10 minutes early and even with a short training session, I was on the road in less than 3 hours. I had the fully automatic system installed, but can use it manually if desired. With labor charges, the total bill was just over $4200.00. My only regret is that I had not had them installed sooner. Words of advice to anyone going to Quadra - pay with cash or check because they charge a little more if you want to pay with a credit card. Also, watch their website because they occasionally have a sale on the labor charge or the levelers.
