Little or no mechanical knowledge or capability

Do you have someone else do everything for you at home? This isnt really that different. Each person has their own skill/appitude level and then determines what they are willing to do themselves.
My first suggestion for you though would be to attend an Escapees club "Boot Camp" program. Much of it is based on needs for full timing, but it also covers the basics on maintenance. Some time getting comfortable with what you will be dealing with, may make it easier.
