Robert,
In my opinion, your above schedule would be fine for a motorhome. Ours is currently sitting in the storage garage for 2.5 months before we take it out again. We do keep ours moving as we travel about 8,000-9,000 miles a year.
Generally, the generator needs to be run monthly for about hour under at least half load. They say do not start a diesel engine unless you are going to drive it at least 30 miles to bring all fluids up to operating temperature.
Since ours is located in the Southern California desert, we don't have moisture problems so with me skipping the regular monthly generator start would not be a problem. This current 2.5 month storage is rare for us as we seem to have ours out at least once a month. I love the RV lifestyle.
