Off hand I don't remember the year but we had 1976 Prowler Travel and a 1984 Dodge window van. We were coming back to our home in Penna. about 1 AM Monday morning from a NASCAR race at Rockingham, NC. on Sunday. My wife was driving, we about a 1000' before the Potomac River in West Virginia on I-81. The Potomac is the state line between Maryland and West Virginia. She had just passed a semi that just happened to be owned by the Rockingham track owner and was still in the passing lane with a slight left hand curve. I was laying on the bench seat just behind the captains chairs, our daughter was on the next seat back along with our dog. All of a sudden all hell broke loose. As i reached between the dog box cover and her seat to hit the brake controller we rolled, did not know we rolled until I found our heads on the roof. All of us crawled out onto the grassy medium, but we were now pointed south as we had been traveling north. The semi driver was the first on the scene and checked us out and helped. Shortly the first state trooper on the scene and he checked to see that we were OK, but he also said that he really couldn't help because he was a Maryland state trooper and the WVA trooper would be there shortly. The van was upside down, the Prowler was right side up, but it looked like a bomb went off inside. After things got settled down, the MD. trooper approached me and very quietly said "if you are in the market for a new trailer see me at a RV dealership" in Hagerstown, MD where he worked part time. That Monday night we went to the salvage yard where they stored it to get some personal stuff. The propane tanks were still in the rack, so I asked them if I could take them. The operator said "take anything you want". For kicks I pulled out our 12 inch AC/DC TV. Later I that week I plugged it in and both voltages worked, now that sucker had to be like a basketball moving around the trailer. Fortunately no one was hurt, just stiff and sore for several days. What we think happened, WVA had just poured new concrete lanes on the northbound side but had not yet built the shoulder up level to the concrete. Since she was still in the passing lane after passing the semi, the tandem wheels dropped down on the shoulder and she over corrected trying to get it back on the concrete. The Prowler of course was totaled. The Dodge van had a new roof and passenger side door replaced, some body work and repaint. At the time the local Ford dealer had a state of the art body shop and that is where insurance took it. Stopped by and said "I will need that January 30 to go to Daytona" Would check every once in a while and it didn't move. So at years end I stopped in again. The wreck happened the last weekend in October. So they finally called it was ready. Our daughter took me out to pick it up. Fortunately she had hung around cars for years. We get home, she says "check the right rear wheel, it wiggles. So I checked the lug tightness first. Nope, they were ok. So then set-up the high tech jack stands and mason cord. Yep, it was wiggling. Pulled that wheel off and put the spare on, wiggle still there. Removed the wheel, re-adjusted the stands and cord. Sure enough, the axle was kinked. Went out to the body shop first thing the next morning and quizzed them. Didn't believe me as they repeated what I did the night before. Next day, we are heading to Daytona. Claimed they couldn't get an axle shaft. I went to a local salvage yard, picked one up, thru it and the floor jack in the back of the van and off we went. Absolutely no problems the whole trip. Finally sold the the old girl with 332,000 on the clock, she was a tough old gal.
