Most of those Tonka vehicles are in 1:18 scale, so they do match up with the Joes pretty well. My son has some of them like the ambulance, garbage truck, tow truck, etc. They all seem to put the electronics in the truck cabs, so hardly any of them allow you to put figures in the cab sections.
I saw a decent firetruck in the same scale at Target, in the blue box aisle. The figures with it weren't as cool, but you could fit figures inside of the cab.
