Lifting an Airstream? Ground clearance?

Hi helpful friends!

Just got a 2008 int sig 23d

We do a lot of off-road camping and hunting... I noticed that the underside is pretty low to the ground(I'm sure normal airstream low, not unusually low), especially the black abs plumbing on the shower rear of the trailer.

I'm a bit nervous about going to a few of our favorite destinations.

So my QUESTION... How do I get 2-5" of lift on this beauty?

Thanks!

The most common way of increasing the ground clearance is to replace the axles with new ones built with a greater downward angle. At ~$750 per axle delivered, with a self-install, it is a pricey way to go, but probably the most trouble free, and least of a hack. This will get you a few inches (2-3) of clearance--it would be tough to get 5" without some serious surgery (ie., rebuilding axle mounts and lifting the entire trailer several inches above the axle mounting point).

I would suggest doing something cleaver with air shocks to adjust the ride height, but the standard shocks mount in an almost horizontal configuration, and only have about an inch of travel, so again, some reinvention of the trailer would be required.

good luck

You are going to have to search for them but there are a couple of threads about raising our trailers using some sort of axle risers. They are a shaped block that goes between the axle and undercarriage. People that are using them here seem satisfied with the results.

I moved your thread to this forum as your question fits in this forum.

Assuming the trailer has horizontal shocks, there is no air shock made for the application. The only shock absorber that will work for the application is one and that is sold be the company and the dealer network. There is no aftermarket shock.

Due to the design of the axle system (a torsion spring axle) raising the trailer becomes difficult and costly. Basically you could raise the trailer off of the axle assembly as stated above. However there would be a point at which control of the trailer becomes an issue.

In my opinon, the Airstream travel trailer has evolved from something that was shown touring the world to a higher end trailer that leads a rather cushy life. The design isn't really to be used off road other than to be put in a camp site. The axle system and running gear are designed for a soft ride. This puts the user at some disadvantage when the road conditions or even camp site conditions become something more than benign.

I have to disagree slightly. The OP original post was regarding the distance the drain valves are below the trailer. If you look at the 1970's and perhaps the 1980's trailers, the drain valves are tucked under the bumper and take very little ground clearance. The newer trailer have drain valves sticking below the trailer like a SOB.
