Just a note of praise --I purchased a set of airlift airbags from Summit racing which I mistakingly found on the internet. The best was by going thru them and not Airlift's site I saved close to 100 dollars. that was on the airbags alone with free shipping. Then I went looking for the controll setup with the compressor and gauge and saved over 100 dollars over Airlifts site-with free shipping. I received the bags the next day and in the package was a coupon for another 20 dollars off the next purchase which I used for the compressor kit. I was talking with the sales clerk and he suggested a pillar gauge pod set up with a tach and airbag gauge since I don't have one on my 2000 coachmen I just purchased . I got everything I needed from them at discount prices. every one was polite and knowledgible. And almost next day delivery. Just thought I'd let you know cause it mostly known for just racing goods. Summit racing--really good tool catalog to.
