Must be the boater in me but I would pay for a smaller much better quality rig with much more water & battery capacity for dry camping. There is nothing wrong with dry camping in comfort.
I know, I am bucking the trend which still follows the American 'bigger is better' mantra. I don't want room enough to square dance in the middle of the 5er. I want a usable galley so that cooking is not a chore of moving stuff around to prepare a meal. I want at least 100gal freshwater tankage. I want commercial grade running gear under the trailer, not barely meets spec stuff. I want the 12V system on circuit breakers, not fuses.
Unfortunately most of what I want is unseen & it is not cheap. Most want the bling & they want it cheap. Then they complain about how cheaply made the unit is.
