Upsizing from a Truck Top Camper?

We have both TC and 5er started with TC. We now starting to travel more for extended times or what some call touring. Boon docking is a very open term. We still boon dock or dry camp (NO Hook Ups) with the 5er. I am keeping the TC for quick two three day fishing trips and hunting trips. I think for a lot of us with TC it comes down to are we camping or touring? We are getting ready to take a 21 day trip to So Cal Disneyland, Lego land, Sea world, San Diego, Joshua Tree, Death Valley. This is a trip that the 5er much more comfortable, we have done most of this trip in truck camper many times and did fine. If we were sticking to weekend trips or one week or so a year we would just have the TC. Now we are taking trips for 1-2 months that's when I want the comfort of the 5er. I t6hink it just comes down to comfort level and how you travel. Yes you can travel and cross the country in a TC, but so far for us the 5er is much more comfortable and just as easy to travel with.
