Most travel trailers are made of light construction so as to not use much gas for transportation. The light duty goes all the way down to the utilities, plumbing and wiring, which are not long lasting. Unsupported the sides would probably cave in if the trench caves in, and untied down these units would surly be picked up by the wind. I think 300 mile/hr winds would tear it apart, especially if there is any debris in the wind (like flying trees and rocks). I personally think by the time one gets done with the cost and effort of beefing everything up you could have built two domes. In general it is probably safer and cheaper to live in a tent before and after the pole shift. Build a cellar or a small dome to stay in during the pole shift. Bury all your supplies and building materials to be dug up after the pole shift.

In other words, we should not spend our precious resources in strengthening a travel trailer in hopes that it would survive the pole shift. Instead we should plan on building a shelter that is more likely to survive. I agree. Tent dwelling up to and after the pole shift also sounds like an excellent idea (and what most of us will likely wind up doing), but what about living in a travel trailer? It would give one more of a sense of security and more shelter from the elements than a mere tent can provide. This, in my opinion, will provide mobility and that certain sense of home that will help alleviate depression. Of course that doesn't mean that a person should attempt to fortify their trailer in hopes that it will survive, instead they should plan on building a small dome for shelter from the pole shift.

Most definately if one has a travel trailer, use it up to the point of the pole shift. Just don't plan to be in it during the pole shift. There may be some exceptions, but for the most part I figure there are three options for cars, RVs, travel trailers and other vehicles. Abandon it and let it blow away, bury it, or build a special garage-dome for it. Most of us will not be able to afford the garage-dome. As an alternative, one could dig a hole, drive the vehicle into it, cover it with plastic and cover with dirt to the ground level. This way you may have some parts and raw materials to salvage after the pole shift.

I agree that a small Monolithic concrete dome could be built for about the same amount as a fortified travel trailer. Materials for the finished shell are about $15/sq. ft. You could finish it nicely for about $30-40 /sq. ft. A 24 ft diameter dome is quite livable for 2 people. You could build it yourself for approximately $14,000 to $18,000. While you lose the mobility, it will withstand earthquakes and 400+ mph winds.
Travel trailers have another little known problem. Many use urea formaldehyde insulation. This type of insulation outgasses formaldehyde vapor for years. Extremely unhealthy, not to mention what happens if it burns. Make sure if you buy a trailer, it does not use urea formaldehyde insulation. The safest insulation type would be some type of urethane foam insulation (either Isocyanate or Polyisocyanurate.)
