I have a 2020 Trail Boss LT with the 6.2. It's about as close to a Raptor as you'll get from GM. I have 3 kids, ages 10, 6, and 2. All 3 fit in the back seat just fine. They have plenty of space. With the offroad running boards installed, my 2 year old can climb into the truck an up into her seat on her own. I seriously considered getting an AT4 with the diesel, and if the 6.2 hadn't been made available I likely would've got it. I currently find myself taking 5 hour one way trips for my son's baseball tournaments at least once per month, and kind of wish I got babymax. However, I didn't know at the time of purchase how much COVID-19 would affect routine matters in my life. That doesn't mean I don't like the 6.2, but the mpg of the babymax goes a long way. My general lack of familiarity with diesel engines also had me second guessing, so I stuck with what I already knew -- GM gas V8s. Engines being irrelevant, I love my new GM truck. It's also the first truck I've ever owned. You also said you're looking to buy a travel trailer. That's a no-brainer: AT4 over Raptor. The softer suspension of the Raptor hurts its ability to tow.
