I would also consider trading for a full-size skid steer or maybe a truck.
A wheeled skidsteer with cab/heat such as a bobcat s185 or the equivalent would be ideal.
something like an f450 or f550 with 12' or longer dump bed or possibly a cab and chassis, 2000 or newer, automatic tranny. Or possibly a low pro gmc or chevy with at least 12' bed but 16' would probably be ideal. Must start easy in cold climate.
