    nice. Now WHY don't they just put this stuff on at the factory? Probably because they're hoping the RVs won't last…… so people will have to buy another one….. planned obsolescence.

    Thank-you for sharing this . I just bought an older motor home that needs to have this done ( as well as other things ). Now I am able to do it right and it will last many more years .

    Hello, wondering if you might be able to help me…so i just bought a 2007 itsica spirit Winnebago and it was in a flood about 6 months ago. The original owner said it sat in 5 ft. Water for 3 days. The stove, microwave, and electrical still work, but it doesn’t drive. I am wanting to have the engine fixed…so I guess what I’m asking is, can this Winnebago withstand flood waters like this and comeback to being a good and save motor home? The engine has 60k miles on it.
