This is the kind of thing we are looking at with Disabled Explorers...
As our population here in the USA ages more and more folks are going to be looking for solutions like this...
Not to mention the women and kids factor...not being sexist or age-ist...just reality.
Having said all that I have not found a solution I like better than either setting up the PETT in a shower privy or ground tent. Not a fast solution if the break is needed during the day.
I have thought about mod'ing up a side awning that had side skirts that were perm and would drop down quickly to make a side room for such a quick trailside break.
If anyone finds a trailer that fits this need please post up as I am sure there are lots of interested folks.
