Now on our 8th RV. 3 of them have been trailers. I've enjoyed operating both our moho's and the trailers (not so much the 5ver). The only one I was never comfortable with was the 5th wheel. Even though I had it matched well for my tow vehicle it always seemed as though I had too much mass behind me-- and a couple of times went through some red lights in wet weather when I could not stop. While it was comfortable for living it just wasn't as comfortable when driving as the Class A's and C we owned.
The A we now have has been the most comfortable and is easy to drive. A's (or C's) are much easier to get into a back-in site or driveway than trailers. The A is easier with our dogs and give the DW the option of moving around a bit in travel. Its always cool with the A/c running, when the trailers were always hot during the summer. And it always has power with the genny running.
Yes maintenance costs are higher with the A.
Like trailering, situational awareness and spacing are essential in an A. After making sure I had made all the steering safety and control adjustments possible we like it better than cruising in a car and far better than trailering.
We drove our TC from GA to Alaska in 2014 and were ready to kick the doors off the pick up after 7 weeks of travel.Last year we drove it in a class A. Visibility and overall comfort in the A made for a great trip. Loved every minute of the A trip and could have gone longer than the 8 weeks we took.
