Some people go camping, they set up in the forest or at a campground for a week and "enjoy nature" or hike or whatever. If this is what you like to do a trailer may work fine and be less expensive.
My family travels via RV, we visit museums, historic sites, relatives, etc. while traveling around the country. We rarely spend more than 1 or 2 nights in the same place. For us a motorhome makes more sense. It allows for snacks, bathroom breaks, naps, etc. to all take place while in motion. (Except for the driver of course.) Thus, since selling my TC a few years ago, I'm looking for a MH.
I'm looking for a class C for a few reasons: I want a driver's door, I want the overhead bunk as we have 3 children and don't want to be converting the dinette to a bed every night, and I do my own vehicle maintenance and a C strikes me as being easier to work on.
I'm a Chevy guy and have had excellent service out of them. I've had a truck with the 8.1 and Allison and it was great. In fact, all of my GM trucks, gas or diesel, have given me fantastic service.
However, if I had to have a Ford engine it would be the V10; no, they weren't perfect but they were pretty solid with a nice flat torque curve.
