Class C vs 5er - Family of 4-5

We love our C, and although Rosie and I usually are going it alone ( with the Josie Beagle), when the two granddaughters go with us, there is a lot more comfort and safety. There are seat belts in the dinette area and the sleeper sofa. I put a foam tube on the table edge for added safety, if there would be a chin impact from a sudden stop. Rosie can always grab a treat or drink for us, or the kids get accompanied to a bathroom if needed. And when we stop for gas or a rest we can stretch legs or the kids can jump around on the bed for a bit.
I personally don't feel like disconnecting the truck from a 5th and leveling etc. , but I'm sure I would get used to it in time. Also the cost of a $35,000. Pick up, just isn't something I need.
