The old time and money bit.

I like Blevi's idea. I myself bit the bullet and got a Yakima for the roof of the burb. I can hold about 4 bikes up there.

The bumper support is the "shell" not the frame.

Adding all the weight you want to to the frame, just makes it harder for the shell to support the frame, because of the added weight.

Monocoque, means a load bearing shell.

That's the principal method of construction of an Airstream trailer.

So, beefing up the frame, adds weight to the trailer, costs you money for the steel and labor, yet adds nothing to the integrity of the shell to frame attachment.

And as an added negative benefit, the more beefing up someone may do to the frame, rearward of the axles, adds weight to the trailer, AND, removes some tongue weight.

Take the advice above. When we got our 67, it had a nice, square hole in the back bumper (guess what that was), and one really bad case of frame separation. The hole is now gone, and so is the frame separation, but only after some major elbow grease and a wad of cash.

If you don't think it matters, try holding a 5 pound bag of sugar on one end of a ten foot long pole, and lift it by the other end. It is much different than holding that 5 pounds in your hands. Then, while holding the same 5 pound bag of sugar on the end of the pole, jump up and down with it.
Our trailer suffered (and it's still not right yet) rear end sag from just the added weight of a 10 gallon grey tank all the way in the back, and 10 gallons of water weighs 80 pounds. This would be the equivalent of 50 pounds of bicycles and 30 pounds of mounting hardware.

Why don't you use one of the bike carriers that are made in Canada and mount on the front tongue. The bikes are carried above the propane tanks. I've seen one of these and they work well from what I was told. There is a trread about these on here somewhere. Here is a link to their website.

Here's what I use...








The total weight of the bikes and rack is probably less than the weight of a 2" hitch receiver and bike rack without the bikes. I would agree that installing a 2" receiver might be a mistake, but I'm comfortable with this custom setup. If it causes any structural problems I'll be sure to let everyone know...

Dozens of people have already posted, that it "WILL" happen.

But, it's still your choice.

Again, Airstream will void any warranty claims as a result of what you want to do.

That in itself, states their position.

Hi Andy:

So what was the length of Airstream's warranty period on Garfield's 2001 travel trailer? Has the original warranty expired, or is it still in effect?

That a good looking and well engineered rake. The one I use and have use as an illustration is no longer available so if you would can you post the maker and modle number. There are lots of Airstreamers looking for this.

Can you post a closer picture of how it attaches to the upper section to the rear of the trailer.

I am sure his warranty has expired.

The point was Airstream says, NO NO.

But as always, it's the individuals choice.

But choices like that make service centers happy, in that "A" they charged you to do it (usually), and B, they charge you to fix it. They can't lose, but the customer, as many have pointed out, will, in time, see the negative results of that choice.

It really doesn't matter to me, because it seems that no matter how well the resulting problems are documented, some people still have to do it.

Andy

Guys (and gals), the question has been asked, answered, rebutted, discussed, cussed, hashed and rehashed. At this point I think anyone that looks at this thread will have a very good idea of the pros and cons of making this suggested modification to their Airstream. At this point I think any further discussion will just be a further review of points already made, so unless something drastically changes in the future, we should all consider the subject closed, and let future viewers make their own decisions on what is best for them based upon the facts and opinions expressed here.
Thanks for keeping to the subject at hand, and not allowing things to degenerate into arguments and personal attacks, it's nice not to have to step in with the ol' moderator hat on.

Considering this topic is posted at least once a month and will posted again I would ask that you leave it open long enough for Garfield to post the model number of his rack.

Are we here to provide open discussion and information or just tow the company line?

That's why it's still open.
