about my MaineCat. All the tanks are easily accessible and replaceable. In fact, a couple years ago, I up-sized my central fuel tank and was able to basically disconnect the hoses and drop it in and add new hold down straps. Sweet. I also, ah, ahem, inadvertantly introduced a carbon based, petroleum type product to my drinking water supply. It was an easy and quick fix to isolate the tank, empty, remove and replace. No issue with trying to wash and rinse and recondition fruitlessly. In fact, accessibility for almost any and all repairs/replacement is outstanding. (now doubtless I'll find some nifty neato project wherein I'll have to eat my words)
