You have a choice of several models. The HWH System Camping World sells, The Big Foot System and The Equalizer System. I had The Equalizer System installed at a local family shop. All three system work well. The cost for my system ordered and installed was about $6100. I believe The Big Foot System is a bit cheaper especially if you are able to travel to their facility. I have heard they can install it in one day. Some have auto level feature/option. It depends on what you want on it. My system has a blue tooth feature plus auto level. I can operate it with my cell phone outside the coach. They are extremely useful and make it more comfortable when walking around inside or sleeping.
