Propane conversion anyone ?

[alberta mac]

Here I am again posting up all my questions in my quest to purchase a Tundra !

Although I still haven't found out the price definitively of propane yet through searching.

The questions is : has anyone done a propane duel fuel conversion ?
is it worth it in dollars, saving weekly fuel costs ?
Tundra computer : wondering if propane will require much work or programing to operate on duel fuel propane ?

Thanks
Mac
