Off road/rough road handling

We have not used my new TM yet (2720SL).
I have been reading the forum, and from some of the posts, it seems that the TM has problems on rough roads. The problems I have read about are:
1. Stuff working itself loose (tables, ovens, etc.)
2. Uncomfortable ride in the TV
3. Dust all over

I'm not really concerned with #3, I'm willing to clean the dust off.
But I would like to avoid #1 and 2.
We went on a 4 month trip to Alaska (from Georgia) with an Aliner in 2008, on some pretty rough roads, and we had a couple of things getting loose, but no problem with the TV ride. We would like to repeat the experience at some point in the future, so rough road handling is going to be important.
I would love to hear what strategies you have used to improve these problems; also, since next year we will probably buy a new TV, what would be the best choice?
I feel I'm taking advantage of everybody's expertise right now, I promise I will try to contribute something useful as soon as we actually go camping in the TM!
