New Wrangler owner here, and I am moving off for college in less than a couple of weeks. It should be known that am making my transition to a Jeep from an F150. That being said, I have to purchase a mattress and box springs while up there. With my Unlimited, I know I cannot just put the mattress on top without damaging the hardtop. The manual warns against it, and common sense dictates. So, already being in for college and a new Jeep, I am not trying to spend 500 or more dollars just on something that I cannot guarantee I will use frequently. Are there any cheap alternatives other than Craigslist or a trailer (oddly enough I have been hard pressed to find what I am looking for in my area) that someone in a similar predicament took advantage of? Also, the mattress is more than likely going to be a full at the largest, most likely it will be a twin. Another key piece of information is that I am buying this local and will not be reaching above 35 mph. Thank you for taking the time to read!
