I hit send before noting that you're in Canada. Canadian law requires
that all portapotties be permanently installed and fitted for pumpout.
Since most mfrs offer models that are designed to be--look for an MSD
designation in the model name/#--this won't present any problems. The
best quality IMO is the SeaLand Sanipottie...their 964MSD holds 3.2
gallons, their 965MSD model holds 5.6 gallons. Price for the 965 is
about $125 USD at West Marine...you can prob'ly beat that price by quite
a bit if you shop hard.
