welcome aboard, fellow canadian, most people on this fourm like the 466 the most, me, well Im haveing fantastic luck with my t444e(7.3), havent towed yet, but will be. you have to look what kind of shape, how the bus was maintaned, miles, and type of tranny, these things will have to be factored in before you buy, I looked at lots of bus, I choose full size bluebired with the t444e, it was the best maintaned, and least amount of rust on it.
just my 2cents btw i see your a dodge boy eh!
