Back from my Columbus Day Weekend trip. We had full hookups but as per usual I let it fill up before dumping. No leaks! Winter is coming with some extreme changes in temperature. I guess time will tell if it holds up. What didn't hold up was the GM HEI ignition coil. I moved the rig forward to get a better angle on the sewer hookup, dumped, and then it wouldn't restart. A quick check revealed no spark to the plugs on the 454. I got a ride to the auto parts store, got a new coil (which I also happen to have in my garage at home) and it was good as new.
