Class C vs Trailer for Cross country with family? Help

I doubt there is a definitive answer. RVing with 5 is tough. A MH owner once said "I don't care how big a MH is, it's really just for 2". Sleeping might be the easiest part. It's meals and being all in during bad weather, etc. But no doubt you're determined to make it work. We've had pop-up, trailer, small 5th wheel and now a 30 ft. MH towing a small hatchback. I prefer the MH and having the car to run around in. We have a queen bed and would sleep 3 kids. Not saying easily.
