i used to watch the triple axle on the 34's i had in the mirror as i rolled across some speed bumps, it was like the trailer never moved. the only advantage i see in the axle setup now days on airstream and avions is you don't have to use a jack to change a tire, that should show you something, its not the tv that beats the hell out of the trailer its the axles.
You know, it always looked like a good deal to me also. All except I never figured out how that center axle stayed straight with a shackel on each end of the spring.

It's like the joke about the thermos bottle...."how do it know?"

that center axle could only go up or down. shakles hold them in place.
in case you didn't know, they make a heavy duty axle shakel joints that have a grease fiting on them that you can add to setup. had them on a 84 30p i had, nice. the old ones do wear.

The next time you see a three axle Avion, take a look at how the spring for the center axle is mounted. It has shakles on each end of it. So, the shakles let it travel foward and rearward, within the travel limits of the shakles, as it wishes.

How weird is that?

Better compare published weights. And owner reports. Airstream since the 1990's are the fat boys. My "terribly heavy" 1983 34' Silver Streak weighs the same (a bit less) than a modern A/S 28'.

An A/S "should" tow better given lower ground clearance (I believe), fully independent suspension and slightly better aero qualities.

We could also probably make up any differences on the weight scale for one TV and two different TT's in re hitch rigging adjustments (given similar floorplans and supply capacities).

I suppose we orta have us a shootout and load two otherwise comparable trailers to .85 or .92 of GVWR to see how it goes. I note that the Scangauge and Ultragauge will both give readings of engine load percentages. A closed loop and several drivers with several TV's and some of the engineering types around here to set definitions of "how to".

OK, so explain to me and everyone else how the center axles stays aligned at all times, that is, if you know.

Sure, the rabbit is faster than the dog, but please explain what the speed of a rabbit has to do with the centering of the middle axle on an Avion.

Hi guys,

I know rabbits and dogs are fun to talk about but I think the original topic was something more inline with a tow vehicle that might be too much for the trailer.
Lets try to get back on track...

Thanks

Vinnie

Vinnie, sorry about that, that steve got me side tracked.
i was trying to say that the TV in not the problem, i truely beleve that the axle's that are used in airstreams are at fault. they do not absorb the shock from road bumps and pot holes. you can lay a 2x6 down on the groung and pull the trailer up on one and it will lift the next tire off the ground. the axle has very little travel, so the trailer takes a beating.
