Tom Raper RV in Richmond, Indiana always had hot-dogs and fountain soft drinks in their show room store. We always made it a point to stop in when we traveled that way and grab a dog, look at the new campers, and usually get a do-dad of some sort.
When Camping World bought out Tom Raper, the hot-dogs and drinks stopped, and I did not any more. Now I just keep driving on down I70. I kind of miss that after all these years. Oh well, things and times changes. Nothing remains forever!
Actually, now when we travel, we like to stop in on the Spartenburg, SC Camping world. They've helped me a few times now, and we've bought our "do-dads" there, since we drive past there (too) at least once a year (From near Indianapolis). Been to the Indianapolis store many times as they are closest. They did have hot-dogs once, a few years ago. We hit it just right. That store has done us OK too over the years. We did buy our second trailer from that location when it was still Stouts RV.
The hot dogs are a nice treat! But as others have said above, there is no such thing as a "free lunch."
