You need to get familiar with the different layouts. You may buy one only to find out it's not what you want/need. For instance, our first 5th wheel was a rear living. Fine for a couple. Terrible for kids. We had no idea. Now have a bunkhouse and are way happier. You'll see rear living, rear kitchen, bunkhouses and maybe other variations. I have pulled two different 5th wheels with that 5.3 Chevy with no issues. I just stay under 27' and pin weight under 1300 lbs.
