Understand the delima and it's all about which compromises work for you.
When I had a FW, with a couple minor exceptions, when I went someplace, the entire family went with me. Those few exceptions was on a long 8 week trip when I would give the kids and DW a late sleep in day while I went to the laundromat to take care of the laundy.
Now, it's just DW and myself. The TC works perfect as we very seldom stay one place more than a couple nights. So when we leave, we rarely have plans on returning to the same campground. The wandering is why the TC works so great at this point in our lifestyle.
If you moved up to a hardside with electric jacks, you would get rid of a lot of the cons for the tc. But it seems like a lot of money you don't want to spend on making the toy hauler work. Unless you are willing to forgo some of the ammenitites by just going to a cargo trailer with some drop down bunks.
