Since weight is a critical issue, I used to carry an AB machine and 50 pounds of dumbells with us, but then saw on another RV forum, that someone ditched all that for 8 pounds of workout equipment. So I bought the same system, and besides walking and hiking and washing the truck and RV, I use this piece of equipment that comes apart and fits under your bed, or couch. Here is the link.
