Brian,

I have read all the responses and noted that no one has answered your first question regarding having the rusty tank cleaned. I
would suggest you Google "Fuel Tank Cleaning, Washougal WA" This should bring up companies near you that can perform that service.

I did that in Houston and found a couple of companies, however, their services were not cheap, I got them to provide a "rough"
estimate after providing the measurements and capacity of the tanks and was told $400 - $500 per tank.

I store my coach in Houston 8 months per year and before I do so I fill the tanks all the way up (adding the correct amount of
Stabil) until I can see fuel in the filler neck at a station about a mile from the storage facility. I drive it back, pull it into
the "garage" and shut it off and don't run it again until the next year when I return. I've been doing this for six years and have
had no problems.

Regards,
Rob M.
