Trailer Trouble

On our way home from Dunnigan on Sunday our Trailer came up with a very flat tire. We were able to safely pull over in Williams and a wonderful mechanic from Colusa saved the day by coming out on a Sunday evening to fix it.
The event solidified a sneaking suspicion that we have had for some time now... our trailer is not in good enough shape to make the drive to Texas. If anyone has a horse trailer that you wouldn't mind lending out (or trading us) from September 10-25 let us know! We would prefer one with living quarters so that we could save on some hotel costs, but let us know what you have.
Any ideas would be appreciated.
