lincolnmattews,
Not obsessed but I know what service and use we've gotten from our 3 Lance TC's and you don't. I'm the one who has to fix or repair if it needs it or take it to the dealer etc to have an RV fixed. I'd thank you for NOT telling me that even our Lance wing rotted as you don't know what you're talking about!
Our 1997 Squire 4000 optioned out was ordered new in the summer of 1996 by us, traveled over 140,000 miles including Alaska and every continental state including all but 3 Canadian Provinces. Sold to a friend in 2009 and it did NOT have any wing rot and still doesn't now 5 years later. Our friend re-sold it this past fall when he'd bought his new larger Lance as his 2 kids had grown since 2009.
None of our purchased new 3 Lance TC's have had any wing rot or leaks if you really want to know. I never removed any molding etc either to re-seal/caulk as it sure wasn't needed. We still see the 1988 Lance TC around town on a pickup but I haven't climbed under it to inspect the wings of it lately but they sure look normal.
Might be the price you pay for living where you do as you live in the NW and have so much constant wetness with so much rain and drizzle etc but most people who have Lance TC's etc don't. I only know of one Lance in our area that had some wing rot near the bottom of the passenger side wing. He said that he dried it out with an electric heater and sprayed Thompson's Water Seal (the petroleum based) all over the wood area and soaked the edges a couple years ago and it hasn't rotted any further since. His is a 1999 (15 years old now) and it's his words not mine. Your's always stored inside and the screws rusted away quote: (Of course these were all rusted away.) Getting a little deep? Screws rusted away and stored inside and the TC didn''t fall apart? Magically bonded and held together by the "invisible force of nature" from Star Wars?
I really don't give two hoots what you buy or like as it's your choice but you certainly don't talk for everyone else or anyone else!
