Coincidentally, I'm travelling to Illinois in about eight weeks and going right by Columbus. If the phone number on your flier is correct I'll try calling you in the near future to learn more about your unit.
We just found and purchased a 2009 22' Towlite about 200 miles away at an RV dealer. Looks like new with no visible wear anywhere. No signs that the stove or refrigerator were even used. Going to p/u unit this weekend and have weight distribution hitch and anti-sway installed along with electric brake. I'll be towing with my Suburban.
We're excited about using the Hi-lo for cross country travel in two years when I retire. We have a couple years to practice .
BTW - this site was an excellent resource for determining the type of camper we wanted to purchase. I'm sure I'll be visiting here quite a bit now that we're "owners".
