Get the SeaLand Sanipottie with the 5 gallon holding tank. The standard
model is only 2.5 gal or so and you get more than twice the true
capacity with the larger tank. The upper section is identical either
way. These seal perfectly and never leak or smell. Once you have had one
you won't know how you lived without it. When you climb tall mountains
you need to remember to let the pressure out carefully at times.

The price is much higher for the larger tank model but look for sales at
West Marine and on the Internet. Adding a few inches to the tank costs
the maker nothing but retail is often $40-50 more.
