As I look back at our maiden voyage,actually the first three or four trips, I would suggest that you concentrate on the driving and backing in portion. Our first trip went much like yours without the flat tire. We got very good at setting up, breaking down and hooking up. I became a little complacent with the driving part and sure enough, I got into trouble pulling into a tight gas station in heavy local traffic.
My focus then became driving and all that entails. Have yet to have a second "issue" in this regard. Best wishes to you as you get out more. We love the lifestyle.
