Several years ago I met a guy & his wife that had a Going business in their RV. He was a very good photographer and they would travel to car / RV / air shows and take pictures of guys / girls / couples with their toys. And then take the pics back to their RV where she was good with photoshop. She could build a calendar with different pics, business cards with a selected pic or prepare a studio quality pic in a frame for a keepsake. They had high quality cameras, computers and printers and seemed to be doing OK and selling quite a bit of product - their rig was MUCH younger than ours and about 5-steps up in likely cost!! Just a thought.
