We own M35's and 5 tons. The 5 tons are more meaty there is no questions about that- bigger axles, t-case, a Cummins engine about twice the CI as a multi, much bigger spring packs, larger stance, etc, etc. Most guys for hobby use are going to have a hard time overloading their M35 so the extra capacity of the 5 ton for most is just for bragging rights. The Multi fuels start MUCH better in the colder weather than the Cummins. The multifuel also has a throatier exhaust note than the Cummins (a nice plus!). Power steering is nice in the 5 tons but I think the non power steering on the M35 makes the deuce that more interesting to drive. It's hard to beat a 5 ton on 1600's though for looks. The M35 will get around 10mpg on the highway where the M809 5 tons get around 6mpg. You won't go wrong with either.
