1, boxelder sucks for firewood, burns quick, and smells funky.
2, flotation comes down to the tire size and air pressure.
Mine are foam filled so that equates to about fifteen psi. I haven’t weighed it but I would guess this comes in around 250lbs. I’ve easily had 3000lbs on it but that sunk the tires in soft ground. Other than that it has pretty good flotation.
