After sleeping in tents for ages, about 5 years ago we picked up a 60's model 18ft. Mobile Scout trailer. To some this may be "roughing it," but to us it's the Taj Ma Hal!
If somethinglike this is what you are after, start looking now! You should be able to find something in the 500-1500 dollar range, if all you want is a deer camp trailer. The closer you get to deer season, the more $$$ you will likely have to pay, so start shopping! Good luck!
