While living in Anchorage a few years ago, I bought my first travel trailer, a 1989 16'
Scamp. Shortly thereafter, my wife Nancy and I took it on an epic trip up the Haul Road to the Arctic. On the way up I used the 12 volt to keep the
fridge cold while driving. For some reason the truck alternator failed to re-charge the
battery so it died the second day of the trip. It didn't matter much because I had an ice chest and it never got dark enough to need the
lights anyway. The Haul Road was 400 miles of gravel. The northern half was severely washboarded. We started to notice that the trailer was filling with flour-fine dust whenever we hauled it even a short way. We also noticed that the mosquitos were coming in somewhere no matter what we stuffed in the door cracks. The dust got so bad that the highway department started spraying water on the road to hold it down. This completely coated the truck and trailer with layers of mud. I spent a couple of days cleaning the trailer inside and out when we got back to Anchorage. When vacuuming under the front bunk I found a one inch gap in the carpet. Upon further inspection I discovered that the plywood floor was separated. When I crawled under the trailer to see why the floor separated, I found that the frame had broken clear through on one side. Assuming the frame broke on the north half of the Haul Road, I probably pulled the trailer as much as a thousand miles with a broken frame. I also found out (from my RV repair guy) that my truck hadn't been properly wired to recharge my trailer
battery.
The frame was re-welded, the wiring was easily fixed, the mud came off. I am not sure if we ever got all the dust out of that trailer.
