Most young people can sleep anywhere. Sleeping in the overhead bunk means climbing up and down a ladder and crawling over your bed partner without waking them in the middle of the night or early morning. If you have bad knees or feet, the ladder can be painful. Most class C's with a rear bedroom and RV queen sized bed are 27 feet long. Some have a bedroom slide to make access to bed on both sides and foot possible. It's hard to make a bed with access on only one side and you have to crawl over your partner without waking them. Being able to sleep and get in and out of bed without waking your partner become increasingly important. The need for towing another vehicle is questionable when you can rent a car or take public transportation to tour RV- unfriendly cities like Boston or NYC. Towing can be awkward/bothersome pulling into gas stations and tourist attraction parking lots, malls, etc. RV'ing requires many compromises, take your time learning and choosing wisely.
