Living in a 1971 Winnie here. Great advice from the others. More than rotting rubber there is also rotting plastic, rotting caulk, rotting sealing everywhere, heck, it's all rotten. It's been around for forty years! If it's soft or sensitive to UV, it MUST be replaced. How do you replace all this stuff? More than the cost of materials (they aren't too bad really, few hundred bucks not counting major appliances) is LOTS & LOTS of time and elbow grease, you can't afford what someone would charge, that means YOUR elbow grease. If I had it to do over again I'd go for something newer. I love my Winnie now, but it took alot to get her to this point. And I still have some mechanical stuff left to do, yuck. One cool thing though, because everything was replaced/resealed/re-everything'ed, don't have to worry about nickel & dime stuff now for a long time. Because I did it myself for myself and looked in every crack & dark corner and left NO stone unturned, don't have to fret about it, I know it's all right. And a lot is very custom, couldn't buy one this way.<div>Anyhow, I responded to a similar question recently with a more detailed description: <a href="

I think legally you have to replace them every 7 years (although I can't believe it could be enforced), I know for sure they are only safe for 7 years. They are protected from ozone, etc. by sacrificial materials and after 7 years those materials are ... gone. Try about $180 x 7 (don't forget that spare!). Of course, this could be an issue with anything more than 7 years old.</div><div>I'm not going 60mph down the highway without a complete replacement of ALL brake parts in this bread truck/kite/oversized ice chest (pick one). Roughly $650 if I do all the work myself.</div><div>1 thing though blkjak, I'm a member of classicwinnebagos.com. Some of the folks there claim 9-10mpg (wooo), they say if you keep your foot out of it and relax & enjoy the drive @ 50mph it does the trick. And really, the newer ones aren't much better, about the same. Oh, that's with the 318/360's though <img src="/images/boards/smilies/wink.gif" border="0" align="absmiddle"></div><div>Alot of these concerns are going to be there with anything more than a few years old, the difference is it ain't a mystery with the '70's box. It's a certainty. Saves you the trouble of looking <img src="/images/boards/smilies/wink.gif" border="0" align="absmiddle"></div><meta http-equiv="content-type" content="text/html; charset=utf-8">
