Just found this thread, I'm debating the same thing right now. I just bought a 2023 Can Am Defender HD10 XT from a guy that never used it (low miles and hours and like new condition). I hauled it home with my 2016 F150 w/ 2.7 EcoBoost on my buddy's 18' tandem axle steel car trailer. To my surprise my truck pulled it very well (even through some hilly areas in WI). I sold my 6.5 x10 steel utility trailer because my SxS won't fit on it....now I'm debating what I want to get, enclosed vs open air. My trips will mostly be 2-4 hour jaunts here in the midwest, and then one trip out west each year. Looking to get a 16' in either configuration, and if enclosed would like to get a 7.5' wide. I see the pros and cons to each of them. If I decide to get an enclosed, my son said he would go in 1/2 on it to cover the cost as he would likely use it quite a bit too (and he wants to set it up as a camping rig as well). The gas mileage thing is what is really concerning for me on the enclosed....but the fact that it would keep my machine clean and free of road hazards, and it gives a much better place to store gear...it seems like no matter how little we try to take out west, with three of us in one pickup it is jammed packed full of stuff....
