I have both a TC and 5th wheel. I'd have a really hard time giving up my TC. While I love the space/luxury of the Montana the TC is equal to those in simplicity and maneuverability. I don't have to worry about anything (except height) with the TC. Simply drive and get where I'm going. Once I get there, I can park or camp anywhere. When we bought our first 5th wheel I quickly found several of the state parks in the Eastern Sierras and a few of my favorite beach spots couldn't accommodate a large rig or if they could there were only a few sites large enough. So, I bought an old TC to see if I liked it. I did, so much so that I left my 5th wheel at my lot in Mexico as a weekend getaway. Fast forward several years. We decided to go fulltime and settled on our Montana. They are both so different It would be hard to give up either. If I had to chose one it would be the 5th wheel because it allows us to fulltime with much less risk of divorce
. If we weren't fulltiming I'd have to give up the 5th wheel over the TC.
Now having guests is a whole other matter. I've spent two weeks twice in the TC with the wife and adult child. Every day I was willing to give up all the good stuff of the TC to get my space back in the 5th wheel.
Good luck with your choice.
