Waste tank capacity in 1968 Ambassador

[Headhog]

I need to move a 1968 Ambassador that has been sitting. Unfortunately, the waste holding tank is full and the support frame partially rusted out. I don't want to move it with all that weight in the tank, so plan on draining it if possible. I need to know how many gallons I may be dealing with. Don't want any surprises when I go to dump it in a portable. Thanks, Bill

My 1966 Overlander is 11 gallons from what I'm told, so I'm sure it's the same.

I tested my '68 Overlander and it held ~21 gallons. I think all models are the same except for the smallest/shortest model.

Thanks for the help. I guess I will be ok draining into a 30gal. portable tank.
