What this means
- Seats and gallons as the maker states them. Where a maker prints two capacities, the lower is counted.
- Bigger is not better. Size is the buyer's choice; our capacity score carries half the weight of the others.
- Check the inside dimensions. Seat counts are the maker's; bench depth and fit height decide the fit.
