Henry is a large cat, so we have to have a pretty good sized litter box with high sides. We didn't want to change things and make it a big adjustment from home, so we just got the same type that we use at home. We just deal with the fact of living in a relatively small space with a cat, vacuum every day and place litter box in the most convenient place for us.
The biggest thing we had to deal with was the scented litter in the smaller enclosed area of the motorhome. The brand we use at home was just overpowering and offended us. We now use Cats Pride light and fragrance free and find it does a great job with odors without overpowering us with perfume.
