We prefer not to be out over the weekends when schools are out, so our trips are short during the late June to early September time-frame. April through mid June and September through mid October are for our longer trips.
We often leave the rig parked in the driveway for 6 weeks and have never had a problem with the V-10. Following a cardiac adventure almost 3 years ago, I didn't get out to run the generator or the chassis engine on a regular basis for about 4 months. The V-10 is fine, but the generator hasn't run since! It's on my "to-do"list, but we're almost always at elec/water or FHU sites. At 11+ years (three of them with us), the generator time recorder only shows 51 hours.I'll get it sorted before we put the MH on the sales block, maybe after the end of the 2016 season.
