We just got our travel trailer last spring and this has not been a problem for us. However, I recently have read or heard about a couple of people that have experienced cracked linoleum floors in their RV's. Is this something that occurs frequently? I would assume that this would be something that might occur over winter and probably in colder areas. I am mainly concerned that if this is a problem, is there anything that can be done to avoid this, other than keeping the RV in a heated area over winter.
