This might be a long post. I have a 1989 Coleman Roanoke popup; second owners for 12 years. I took it on its longest journey from Dallas to Durango, another 400 or so miles in other areas of Colorado and then back home to Dallas. Before we left, I purchased new hubs/bearings from Northern Tool and brought spare hubs/bearings with us. So, around 2,000 miles total, give or take. I worried about those little wheels, and the bearings the entire trip. Every time we stopped for gas, I was under the camper looking for a blown oil seal and feeling how hot the hubs were. When we got to our first campsite, I couldn't stand it anymore and took a tire off and popped the cap on a hub and inspected the bearings and much to my satisfaction they had plenty of grease and all was well. All the worrying was for not because we never had a problem and made it there and back just fine. I said all of that to say, I am still worrying about those little wheels! We are going again this summer, as we do every summer. I told my wife and kids we are tent camping this year and they have flat out refused. I hate going so slow....I go 65 mph and I know I should really be going like 60 mph but that's just entirely too slow! And the little wheels/bearings I can't stop worrying about! Anybody else think about this and what are your thoughts, tips, pointers?
