Anyone have experience with Airsafe hitches?

Thanks for everyone's comments. Sounds like it is a good system. I am a weekend warrior but the roads I've been travelling on lately have been horrible. We take the camper out once a month for 4 days at a time. Next year we are planning a month long trip (already saving gas money for that).

I'm basically looking for anything that will help smooth things out. I bought the Dexter E-Z Flex kit but it hasn't arrived yet. I also plan on getting some better quality tires on the truck and eventually the camper.
