One MAJOR safety thing to look at FIRST:
OEM Rubber fuel lines in these old gassers are NOT compatible with modern, alcohol-laced fuels. Modern fuel deteriorates old rubber in a hurry.
If the lines are not brand new and rated for modern fuel, their total replacement should be first on your list of safety upgrades. A raging fuel fire started by a cracked fuel line and a hot engine has been the end of many of these fine vehicles.
As a side note, obtain and carry a large dry chemical fire extinguisher, preferably several. They are a good idea in any case...
And, welcome to the forums--lots of useful information and helpful folks, especially in the motorhome areas!
