Full-timing it with teenagers?? Are we crazy?

We are considering packing up and going full time as a family of 5 and our dog. We have always homeschooled so that is not an issue, my work schedule is on 2 weeks off 2 weeks. So we would have to stay at a RV park near work half of the time and travel the other 2 weeks. Not very many people are approving of this idea, mostly due to them thinking we are traumatizing our kids. We would be moving from a 3000 sf house into either a 5th wheel or possibly class A- thor and newmar both have toy haulers we are considering. Have we lossed our adult minds and just living in a dream? Our kids think it would be awesome and are all adventurous and love the outdoors. But reality is we are all used to luxury and space. I'm concerned what happens if we regret it, we can't get our home back. Any advice for someone who desperately has wanderlust and we are all ready to pack up, put the sign in the yard, and go. BUT the what if's have us hesitant.

Also would love some full-timers with kids advice, is it a struggle? class A or 5th wheel? What are some must haves in a RV when living full time?
