Re: What is so bad about a Porta Potti?
The biggest challenge with a PP is capacity. Which is why larger boats have built in systems offering holding, pump out and overboard discharge and usually 10+ gallons. For lite use PPs are perfect and I used one for two years on my sailboat. They can get quite heavy when full so keep that in mind.
Also DO NOT get the type with the screw on cap on the bottom - these WILL leak. All the of the new ones have a solid bottom with a swiveling pipe to dump.
Heads are Heads and well ... they're nasty! There's no getting around it. :P :P :P
