The dry bath in the AF992 is small compared to the wet bath in the AF990. Also you can’t use the bathroom with the slide closed.
Fishorgolf has a good point about an area for wet items to hang while they dry.
The AF1100 series has a nice dry bath that can be used, for bathroom break, with the slide in. On the AF1140, I am not a big fan of the cook top being right next to the dinette. I am concerned with the cooking splatter/grease getting onto the dinette fabric. I like the refrigerator/wardrobe layout on the AF1150. Also keep in mind that there is a large countertop extension that comes with most AF TC’s. Your truck will handle the Arctic Fox nicely.
