In the end, this seems like different goals - some just want to enjoy nature but not live in any delusion that we need to be more paleolithic to have the most authentic experience, others crave this process more than the end location. I identify more with the former group, and an RV sounds like a better bet for people like that.
I would be curious to know which is the least destructive to the places been to and the environment though. If the RV is worse, maybe that's one argument. But I'm not sure that makes sense - someone who stays in the hotel might end up costing more in resources maybe?
Like poor neighborhoods have so much more community than rich ones because people genuinely need each other to get by. When you're completely independent and don't need anyone, I think you've lost one of the things that gives life its value.
Also towing a Jeep with us makes a huge difference being able to really explore anywhere around where we are staying and see the sights. I really love Colorado and a Jeep is the way to really see it.
If I was single I might have a smaller RV with just a motorcycle, but with the whole family this setup is perfect, and it seems like kids have really got a lot out of it, they frequently talk about the places we been in the RV and love traveling in it.
On the hand, if it convincs you make trips you otherwise wouldn't have made, I think it's a win. I love Road tripping because it forces you to deal with stuff, especially if you're doing it in less developed countries. Probably the most fun I've ever had is driving long distance in Africa. You really never know what's going to happen next!
