I don't want to make things more complicated, but maybe better mentioning this now instead of finding out the hard way. You may or may not have a hassle from your local planning and zoning dept. Some communities have limits on living in a "travel trailer", or age limits on "manufactured housing". Depending on the zoning rules and how strict they are enforced in your area there may be something to be said for not setting the Sovereign
up too permanent looking. You could then always say it is a "travel trailer" and not used for permanent housing. I don't know if this sounds too sneaky for your taste or if where you are there will be any objections at all. Sometimes also the best approach is not bringing your plan to their attention.
