Phil Nichols,
Yes, we all had showers, both inside and out available and we took advantage. However, there is a price to pay when you commit to an Expedition-style campmobile. If you do not take precautions to keep the twisting of the frame to pull your camper apart, you will have woes. We've 'worried through' those exigencies and have now a pretty good platform for true off-road truck camping. From sand dunes to deep snow to washboard roads, we are ready.
This is at the top near the Bristlecones above 10,000 feet. That rock behind the rigs is the ridgeline of the Inyo's. Notice my bro's camper is offset. When we got down the mountain I had to use my winch to pull it straight again. One of his tie-downs snapped.
regards, as always, jefe
