I bought my Class V AirSafe back in 2006. I had been reading on these forums the problems related to using heavily sprung pickup trucks like my F250 diesel to tow Airstreams. Namely, the heavy trucks were said to be complicit in overworking and shocking Airstreams' frames and superstructures to the point of damage. Posts especially by Andy were quite compelling to read. He said the Airstreams were better suited for being pulled by soft-sprung sedans rather than heavy pickups.
Because I seemed to be suffering from this problem, with popped rivets, cabinet doors swung open, the interior often found in a flux and even some torn/cracked aluminum panels in a couple of spots, I bought the AirSafe. Since the day I put it on, all these "shaken trailer" symptoms have disappeared.
I've used this AirSafe from coast-to-coast for the past 10 years. As the state of our nation's roads have deteriorated during those years, the value of the AirSafe has increased. It is an investment I'm happy I made back then. It's still paying me dividends every time I take the rig out on our crumbling infrastructure.
As the saying goes, I won't leave home without it.
