Rear trailer Hitch on 22 CCD For Generator

Hello, has anyone mounted a trailer hitch on the rear frame of their Air Stream for the purpose of connecting a hitch tray to haul their generator? If so, please include pictures of the generator and hitch mount. Thank you! I believe I am going to mount a Honda 3000 generator to a hitch tray and just keep it connected to a rear mounted trailer hitch on my 22 CCD.

It is STRONGLY suggested that you don't do this. The body of an Airstream carries some of the load and if you place more than what is already behind the body, you will most likely get frame seperation which basically means that the shell will start to detach from the frame. Very expensive and complicated fix.

Unless you have an Airstream motorhome, adding a hitch to the back of any Airstream trailer should simply not be done, no matter how small the item might be, the design is not strong enough for the forces that will happen when in transit, off the back end. Do a search on this topic and you will find lots of the same thing I've discussed here. Additionally if you want to verify the info, contact Airstream directly and I'm sure you'll get a similar response.

Just don't do it! I'm certain that nothing good will come of it.

Let me add that Silvertwinkie is right on. That is a tempting storage spot for many folks. There are many posts on the subject here and the unanimous consensus is don't do it. You will damage your trailer.

Not a good Idea. This has been discussed several times. Do a search and read Inland Andy replies about placing a load on the rear of the trailer. Others have placed the units on the tongue and other options. It is not even recommend carrying a bike on the rear of the trailer. Good luck with your project.

What about spare tires? I noticed that some trailers have an aftermarket spare tire holder with a spare tire mounted on the rear bumper.

Nothing means NOTHING, as far as an AS trailer is concerned. Square white box trailers have spares on the back, but don't have the unique monocque construction of an Airstream. A spare tire is more weight than a bicycle in most cases. If you ever have to deal with the severe frame separation, you'll be more careful the next time around.

Generator on Rear

Hello, Thanks for your responses. After hearing these, I am very much concerned about the structural integrity of the 22 CCD frame under the so called normal or designed parameter loads. It appears to me that when one would do a free body diagram of the forces after appropriately mounting a receiver hitch and when considering the load offered by the generator/hitch tray/receiver hitch and the distance that the resulting loads would not be that significant. If mounting takes advantage of both the top and bottom chords of the frame rails, the additional forces would be minimal considering the so called load designed load capacity of the frame. If the tolerances are that tight and the chosen structural components such as the frame rails are that thin to where the structural integrity would be in jeopardy, we all should be selling our trailers.

These were a dealer added option in 1963 (maybe a couple of other years too) but I think they realized it wasn't a good idea which is why we don't see them more years or at all today. Too much cantilevered weight back there...have you ever riden in the back seat of a school bus?

Thanks Shari! It has been so long ago that I have been in a school bus that I have forgot what color they are.

What's with the 'tude???

You asked about mounting things on your bumper then slam people that don't recommend it...huh?

Do what you want...it's your trailer!

MrAgent -- 'Q' would lecture you on physics and moment arms. Grab a big dictionary and hold it close to your center of mass (axle). Now hold it at arm's length for 10 minutes. We haven't even begun... Keeping it at arms length, now start bouncing up and down. That's how a moment arm amplifies force -- making a lever efficient for turning a rock and a simple bicycle efficient for stressing an Airstream's frame beyond its design load. These never were nor will be designed for loads at the back bumper due to most states outlawing double bottom trailer pulling unless the first is a 5th wheel.

One can go by an SOB toy hauler with a mongo frame (that will be a POS in 15 years) or they can consider an elegant Airstream. In the latter case please listen to Shari.

What you don't realize about a monocoque constructed trailer is that the relatively smaller frame is more than compensated by the integral shell in handling the loading within the design parameters. This type of constructon is why Airstreams are lighter and longer lasting than anything else out there.

Consequently, the frame of an Airstream is not solely designed to handle that type of moment weight and the monocoque design will not allow the forces generated by that weight to be properly distributed thru-out the frame/shell construction.

But as Canoe Stream and others have said, it's your trailer and if you don't like the advice of folks that have been there and done that....you are always free to do what you want. Just don't say we told you so!

PS: I also have a Masters Degree in Engineering, so if you would like to debate the inherent forces of any weight cantilevered off the rear of an Airstream frame and the potentially destructive consequences it would create.......fire away!

I say go for it, let us know how it works out.
