Dad looking for family's first camper. Bunk vs. Rear living

Hello all, here goes my maiden voyage into RVing. I find it odd as 10 years ago I admittedly scoffed at the idea of owning a camper as I held steadfast to my opinion that the only real camping was done from a tent. Ha ha ha. Well, with age comes wisdom I guess (and usually better finances) and now I find myself wanting a camper in the worst way. I recently purchased some land here on the Cedar River in Iowa with electrical and water. Since this location is somewhat prone to flooding I really like the idea of having a camper there instead of a cabin. My family, friends and I spend a lot of time on the river in the boat and I just love the idea of having a camper backed up to the river with my boat tied up 20 yards away. Although it may sound like I'm rambling the intent of my setup in scenery is to explain my desire to have a rear living set-up even though I have 2 boys (age 7&9). I love the idea of that large back window with the recliners turned facing the river drinking coffee, watching it rain, ect. The bulk of my apprehension revolves around the almost unanimous opinion that if you have kids you want a bunk house. I have told myself (and my wife agrees) that we can easily manage sleeping agreements with the fold out couch and table. Or heck, my boys almost prefer during on an air mattress over there own beds. Anyhow I would LOVE to hear your expert opinions on this. Am I out of my mind our is the bunghouse trade off warranted for the bigger rear living room facing the river?

I have a 2007 Silverado crew cab 4x4 that is rated for 7500# for pulling.
