However if my primary aim was dry camping I'd want at least a 50 gallon fresh tank and 30 gallon grey and black tanks (more grey, we always run out of grey space even without running showers but ours are 15 gallon not 25).
There's a difference between "dry camping" and "boondocking" as the former usually means camping without on-site services but within an organized campground of some sort where services such as potable fresh water and waste water disposal facilities
are available. That being the case there's really no need beyond convenience for really large tanks when 30 gals is plenty, the key being to have on hand a convenient method of collecting more fresh water and disposing of grey water as necessary. I also have the means on hand to dispose of macerated black water but with a 30 gal BW tank I rarely need to resort to off loading that tank while we're still camping. This said, other than for those actually boondocking where no services are available, 30 gal tanks IMO are plenty. :B
