It is not an easy thing.Especially if you are a smaller supply dealer,loading and unloading more weight than you know you should be hauling,then hours of set up--all by your lonesome.
Pack it up and do it again in a few days.
People tend not to believe you, when you say you make about 2 bucks an hour,but that is about tops for us smaller players.
A vehicle with almost 200,000 convention and trapping miles does not help your peace of mind either.
4 years ago,I slept in the back of my truck 43 nights doing conventions---rather I should say,I laid down in the back of my truck--sleep was another matter.
