I often thought of starting a thread like this one, my compliments to the OP.
We have had our Nexus Phantom 23P for a little over 2.5 years and more than 29,000 trouble free miles. Our 24'C has every amenity found in the big boys with the possible exception of a washer/dryer and "Frankly Scarlet".... We got very lucky in that we found our perfect rig, used with just 6,205 miles on it, at a smoking good price. Happily we were smart enough to jump on that deal and have not looked back.
We did a 7,500+ mile cross country, 22 state, two month trip (May - June 2014), that was nothing but amazing... other than having to dodge more than a couple tornados. :E
We have done 3 to 4 week trips to northern California and/or Oregon 4 times and spent 3 weeks in the southern Rockies last year... all out of our home town of Tucson.
We are in the planning stages of a month+ long trip to Key West this fall and of course will be returning to northern California/Oregon once again in August/September. The key to all of our successful travels are "our travels".
As I learned during my boating career "use it or lose it" is just a simple fact of life. Regular use and maintenance are essential if you want trouble free miles {of course having a quality coach and knowing how to properly/safely operate it helps a great deal}. Whenever anything shows the slightest sign of needing maintenance (above and beyond the routine scheduled variety), it gets addressed.
When not out on the road on extended trips we camp every month, often more than once in any of the wonderful CG's to be found here in Arizona. By altering the elevation we are able to do so year round in complete comfort (the 35,000 BTU furnace does however get a workout during the winter). :W
We take our time, usually cruising 55 to no more than 65 and only on the interstates out of necessity. Our travel days are typically 4 to 6 hours, rarely longer than that. We start and end our days early and enjoy wherever we are even when just passing through. This country has so much to offer and we intend to continue enjoying it for as long as we are physically able.
