I'm about to buy a gmc motor home. The airbag suspension doesn't work. Will it damage the motor home to drive it broken? I want to do a 10 hour road trip before repairing it. Thanks!

Put a Schrader valve in the air bag, pump it up, and boogie. If the bag itself leaks, replace it with a piece of threaded rod. It will get you home.

If you have air bags on the coach, isolate them and install a couple of air tank valves like Johnny suggested:

I once answered a "Black List" call for a couple who had leaky air bags in a new to them coach. I took him to a nearby Ace Hardware, where he purchased some pipe, all thread, nuts, and washers. I told him how to substitute this stuff for the air bag. I got in touch with him later and he had driven the coach over a thousand miles with the rods in place of the air bags without issue. He said it didn't even ride that badly.

I blew an airbag just before a planned trip from Santa Fe, NM to Denver. About a 450 mile trip. I couldn’t locate a bag in Albuquerque or Santa Fe so I went to Ace Hardware and bought a length of 3/4” threaded rod, nuts and washers. I cut the rod to the right length and put it in and drove to Denver. As you say, the ride wasn’t too bad. I was used to looking over to my wife and seeing her breasts bounce up and down but on this trip they swayed back and forth. Especially on the I-25 “S” curves through Colorado Springs.
That rod was enough to make two rods so I made a spare and gave it to a friend. I still carry one in the GMC for an emergency.

We had two new bags waiting for us in Denver and I quickly replaced them.

I think it would be a bad idea. You have been told the correct approach. Try Schrader valves on the bags.
http://www.gmcmhphotos.com/photos/data/500/GMC_schrader_valve.jpg

If the bags only hold air for an hour or so, consider taking a 12V compressor and filling them every hour or so.
If they don't hold air long enough to suit you, I believe Ken Burton has loaner bags if you will pay shipping from him to you and then back to him.

If they won't hold air at all and you don't want to trouble Mr. Burton, here are a couple of temporary replacement ideas:

The link to the air tank valve in my previous reply was an example only and was the wrong size (18" pipe thread) and should have been 1/4" pipe thread like this:

I have edited the original post.
