You make no mention of budget or size. Your TV will limit you somewhat. Personally I like the larger toy haulers for their excellent living and sleeping options.
KZ 3911 / 4111
Momentum 395m
Cyclone 4005
Are the three we like the most and for varying reasons. They are all on the larger side though.
Anyway, having the space back there for beds for the kids while retaining a functional living area and kitchen are high on our list.
The Cyclone 4005 we'd rip out the small slide sofa and put a sectional there that we'd move when the slides come in.
The KZ we'd put a slightly more functional sectional there in front of the counter and in the slide and the momentum is fine as is.
In all cases the rear garage would be used as the kids room.
Good luck in your search.
