RV living is not necessarily easier or less expensive than living in a sticks and bricks home. There is a lot of maintenance necessary to keep an RV in good condition. Are either of you able to do the work yourselves? Do you plan to travel or to stay in one area? Are you both able to drive/tow an RV? What would be your plan be should his health deteriorate and he needs a transplant? There are hundreds of questions like these that need to be answered before you decide if it is a good idea. Keep reading this forum and asking questions. Good luck.
