You can also get a blow-up mattress that fits the bed (07) perfectly,,,,,,,,,and I am only 5'6", so can easily stretch out with room to spare. The wife and I recently slept in the ST with no problems,,,,,,,kinda cozy,ha ha. I keep the tent in the bed in the event of an emergency, like mentioned above, also,,,,,,,,,just handy to have, in case you want to pull over somewhere to get a nap on the road, or when going into the mountains, allows us to camp just about anywhere.
