If you'd like to read about some of my experiences on a washboarded dirt road from about 8 years ago, check out this thread:

The dining table pulled out of the wall, the water heater came out a few inches, the oven FELL OUT, the toilet pulled up enough off the closet flange seal that sewage leaked out into the bathroom, and I lost a bolt from a a shell hold-down latch.
The stabilizer jacks and undercarriage of the TM are the least of your problems......TMs are NOT designed for off roading.
