my reasons I dislike the 2 wheel versions.
weight to lift one end.. heavy.
controlling the speed the water leaves the tank.
making sure when you lift one end of tote .. the other end of hose does NOT move from the ground port.
end of dislikes.
the barker pneumatic tires do not make any noise going down the road..
the pneumatic tires go over gravel Well.
the metal wheel bearings can do 20 mph.. without any heat. 1/2 mile anyway.
the 32 gallon when empty. lift front wheels to truck tailgate, let front wheels rest on gate, raise rear of tote to get tote into bed of truck.
and the waste gate valve is real good at avoiding mistakes/spills.
my opinion
