Anyone out there know how much water or how many tanks a 1978 Bon Voyage twenty footer has or holds ? I found some info. on Hi-Lo tanks that's says 26 gal.-black, 21 gal. -grey & 30 gal.- fresh. It didn't say what years that pertains to. I have a tank up front under pass. side seat that fills from out side,not sure how much it holds,its metal. There is another in the rear underneath the camper which i assume holds the dirty water & the toilet water, when flushed. I'm not sure how much that one holds ,its plastic. Is that what holds the toilet water ? The tank up front must be the fresh water . So what does this mean i have fresh water tank & black ? No grey water tank or are black & grey one tank ??? Hope someone knows, so then i'll know.

Front tank is usually the fresh water tank and on many hi-los it is a thrity gallon tank, but it is plastic. The rear tanks ARE , usually, the black and grey water tanks. BAck in the day trailers used to combine the grey and black water. That is not standard, now. But, it MAY have been back in 1978. Check out the library on this site and try to find a brochure from a year close to yours- preferably 78 or older. that may give you a good indication.
