Triple Axle Question

Hey guys. I love the look of a big long Airstream sportin 3 axles underneath. Not sure why, but I do! Im currently in the process of selling my AS and am wanting to get a 34 footer in its place.

When I was younger, I heard a horror story about triple axle campers. The guy said when your backin em up and turn too sharp, youll snap the 3rd axle. EEK! Is this true or is it just something thatll happen to 5th wheels?

Never tried to turn my trailer too tightly when pulling forward or backing up. I did scuff the tires on the front axle, but it was usually during low speed turns.

Absolutely FALSE.

The tires "skid" in a tight turn.

That being the case, it's impossible to snap a 2 inch diameter spindle.

That makes me feel better! I didn't put a whole lot of thought into it but it does make sense that youd almost be more likely to fold the tire under the rim and pop it off the bead before the axle flexes enough to break.

The fact that there is some skidding of the tires when you try to turn three wheels that are in line on the trailer is the reason the 6 wheelers have better lateral stability and less likely to get in a sustained sway oscillation. The skidding uses up the energy. It is the same as the frictional dampener. When you are trying to make short maneuvers during parking on gravel you can see the skids.

Yeah, that's what the extra length is for...to carry spare axles. I personally would not travel with less than a half dozen extras. Nothin worse than making a tight turn into the Truckstop/ammo/liquor store and popping the rear axle and not having a spare.

I've found out that if you put large 17" tires on the center axle and mini 13" ones on the front and rear that the trailer just pivots around the center axle...no more broken rear axles!

Seriously, the tries skid sideways and in a tight backing manuver, it will make you squench but nothing bends or breaks

I have pushed our trailer backwards up hill while making a 90 deg turn (our driveway) many times. She certainly skids the aft axle, but no damage results. You needn't worry about this at all.

Watching my 40' 5er really twist the tires on u turns on pavement, no issues but I feel bad for those tires leaving stripes.
That said, '07 in Sturgis my neighbor had something close to 47+? feet with four axles 5er toyhauler. He said it was a factory prototype, and worked there, is how he got to test it. He said he got a kick on how the tires distorted dragging them around tight turns on blacktop until he broke the rear most wheel hubs both sides, something about pulling the wheel studs out shattered the cast iron. He was waiting for the new hubs to show before he hit the road back. I don't remember how many harleys were in the back either.
I'm downsizing to just two axles

I don't own a 34', but have towed my friend's in an emergency when his tow vehicle had a problem, and I will testify to the fact that other than a little more weight, the most noticable difference is the increase in stability of the three axle 34 footer.

That actually makes me want a 34 footer even more lol. My 2 biggest concerns when towing are:
A: My hitch is going to fall off and my Airstream will be a mangled mess wrapped around a tree

B: My Airstream is going to start to sway uncontrollably and my truck, Airstream, and me will be a mangled mess wrapped around a tree

Itll at least take care of one of the problems lol

You might stay away from trees.

You might be a bad driver if you swerve to miss a tree and its your air freshener

Anything is always possible, so I have one word for you: Insurance
