FYI Most boats (I would guess over 98%) DON'T have any sewage smell. The 2 or less% that do get the bad press and attention and cause the Newbies and uninformed to seek out other than mainstream alternatives . Some of these alternatives work out and some don't.

In many cases the boat is devalued and when sales time comes the unit becomes a hard sell. By never planning to sell you are in the minority. The normal ownership cycle on boats large enough to have a head is from 3 to 7 years. If an individual is a long term boater he/she will usually upgrade from 4 to 7 times in his/her boating lifetime. Most of these people prefer a boat that has not been altered in any significant way from when it was produced at the factory. The quality boats That were built in the 70's and 80's, that are selling for good prices, are much the same as when they were built except for electronic and cosmetic interior upgrades.

You are unique as is your boat. Most of us are happy following traditional paths. Were just as happy as you are.
