I camp.
I don't RV.
At least that's what I keep telling myself...
Tenting with three kids was great, but it was tough to convince my wife to do it more often, so I was going to buy a pop up.
Then I saw a "hybrid", which is a hard side travel trailer with the pop down ends. You sleep in a "tent" and the rest is pure luxury: full kitchen, bathroom, sofa, dinning, AC, etc.
Now my only problem is finding the time because I'd go every weekend if I could.
As for trailer vs. coach?
Good friends of mine retired several years back.
They got a 5th wheel unit that sits on the back of a pickup truck bed. Reasoning: They wanted to be able to unhook and go without dragging a "toad" behind them.
After one year, they sold it all and bought a Class A motorhome and a small toad (it's called a toad because it's "towed" behind them).
Bottom line: Think about what you want, and HOW you're going to use it. Rent each if you can and try them out.
I love my trailer and wouldn't trade if for anything. There is no higher quality time with my kids than when we're out in the middle of a State Park, toasting marshmallows and telling stories.
And they would tell you the same thing.
