Big Country 3150RL , Have Dexter Nev/R/Adjust brakes on rig . Jacked up the camper to test wheels and the wheels were difficult to spin very tight. Went to the opposing side did the same spin on the tire and it also was very tight. Or should I say a lot of drag. Is this normal?? Have not been on the roadway much only 15 miles. Planning to do highway travel this week. Concerned about the wheels not spinning. New owner of Heartland Big Country Rig. Please advise A.S.A.P.
