'03 wildwood t22 water tanks

[CampBC]

hi guys, today I went and took a look at a (as the title says) 2003 wildwood t22 lite bumper tow trailer, I chose to go in on sunday so I wouldn't get molested by a dealer, also knowing there were some questions I wouldn't be able to get answered. long story short, the compartment in the back that contains the fresh water tank and a few other things was open. and the tank looks fairly small to me, although I could be wrong. anyways I was just wondering if somebody on here would be able to let me know how big the fresh, grey, and black water tanks are. I really like the trailer but when we camp we don't go very many places (if any) that has water hookups, so if the tanks are too small it may not be the trailer for us. thanks in advance.
