We just purchased our first pup. We attempted to move/push the camper into our relatively flat driveway/garage using a dolly. It was nearly impossible (my husband and I are in our 30's and relatively good physical shape). My suspicion is the brakes are engaged. Any suggestions? Would moving a 3200lb / 380lb tongue weight really be nearly impossible to move using a dolly? We have a 2015 Flagstaff HW27KS... not sure it this not is needed to help answer the question.
