So, to all the above:
Being able to park your trailer in your driveway all summer is a HUGE plus.
My BIL doesn't have a driveway (back alley, entire driveway is filled with Garage), so he needs to store his trailer year-round, and go pick it up a couple of days before they leave for a trip, streetparking it in front of the house. You need to buy a special permit to street park a trailer for more than an hour, and then you can only do it for like 3 days per permit. So that's additional cost, additional hassle, etc.
I, on the other hand, actually have a driveway that is large enough to keep a trailer all summer. And I have enough room to to move it to the backyard for winter storage. My trailer (currently my small pop-up, but I have enough room for a larger trailer, too) is on my property at all times, and remains in accordance with all by-laws. This makes it easy to prep for a weekend away throughout the week without any hassle whatsoever. Pack the trailer during the week (really it's only food and clothes...all the rest of the camping gear just stays in the trailer), then hitch up after work on Friday, and away we go.
Part of the draw of having something on wheels is that we can go to a different campground/campsite each time. One weekend we can go on a group trip with friends and family, and all have sites next to each other so all the kids can play together, and we can be social. Other weekends, it's just us, and we can pick a more remote campground, possibly with a water-front campsite, (even if it's battery power, we're set up for that now). We are exploring different places all the times. Sure, we have our favourites that we like to go to, but we always do a couple of new parks that we've never visited every year.
If I wanted to visit the same place all the time, I would just look to buy a cabin somewhere and be done with it. But that's not the experience that I want, so a trailer it is, and a new campground with a different view every weekend.
A different view, each and every time:
