Wow JandVcruise2018 - that's how we "sightsee" when we travel. Due to still working full time, we have to cram everything we can into a one or two week trip. We've never felt like we've missed out, only that we'd like to go back again and we often do. As for your wanting a diesel dually, I don't blame you. We purchased ours brand new in 2011, have maintained it religiously through our dealer so they have all records of maintenance and it still only has 30k miles on it. Now in the winter, we keep the engine block heater plugged in and drive it once a week.
