Directv DVR continuously resetting when no signal from sat

I have a fifth wheel trailer, not a motor home. My thinking is that the damage done by driving a motor home down the road would be much less than pulling a trailer. I have never actually ridden down the road in my fifth wheel, but I have seen the effects on unsecured items after a rough road. Most trailers have no shock absorbers, so I doubt my DVR hard drive would survive very long on a rough road, while towing.
