I have been in a similar situation as you. The first "real" rv I ever had was a Coachmen slide in truck camper. It was worn out when I got it and in bad shape but I fixed her up nice and we used it for a few years. Im sure some looked down their noses at us, but that was never a concern. The bottom line was it was paid for, was what we could afford and it worked for us at the time. NEVER, NEVER, let yourself be concerned about what others think or say, do your own thing as best you can. Now there are campgrounds that dont allow rigs over 10 years old and thats fine, if they dont want my business, I go elsewhere. I have found that many CGs taht say they dont take rigs over a certain age actually will, providing the rig is well kept. Do not worry about what someone else thinks about your rig, its how you feel that counts. Hope you have many happy and fun trips.
