Cyclone has a new model, CY 3418, with full actual 18' garage (not 17.5' like the 4018), but I don't like the layout. No couch, no table. Just two swivel chairs.
Funny you mention TCs. I've been looking at truck campers myself, such as the Lance, Adventurer, Ascent, etc. I have a RAM 3500 Dually so I'm not worried about weight. What's fascinating though is that some truck campers actually have MORE features than the gigantic 5th wheel toy haulers! Both have queen beds, places for your clothes, kitchen (stove, oven, microwave, refrigerator), drawers, full bathroom (even with separate tub in a lot of truck campers), couch/booth/dinette, etc. In fact, some of the larger truck campers even have both a booth/dinette AND a separate couch with pull-down bunkbeds over them as well. But 5th wheel toy haulers, despite being so much bigger, don't seem to add any more counter space, more seating options, or more surface/table space. The closets and refrigerator might be bigger, there there might be more storage space, but most of the additional square footage seems to be spent on hallways and the ability to walk around the bedroom.
Personally I'd rather the bedrooms in the toy haulers were kept small & cozy, and let me use the additional room for a nice big dinette/table and a big reclining sofa. Maybe even a coffee table and a 60" TV or something to make it feel like a real "home". Maybe I'm unique but I really don't need all that walking space around the bed (I don't mind if gal climbs over me ;)) and I think open floor space is wasted space.
Honestly the only benefit I can see to a toy hauler vs. a truck camper + utility trailer is that you can use the garage as an actual workspace/livingspace when your toy is not in it. Also you can boondock for much longer in a toy hauler due to the larger tanks.
I think I'll wait until I'm ready to be a full-timer before I get an actual toy hauler, and in the mean time I'm thinking of just getting a truck camper + enclosed utility trailer. I need to find a truck camper to go visit though so I can check out all the models since nobody around where I live sells them (they don't sell the toy haulers either).
