Welcome to the forum...
Yes, it should be safe but be aware that 64gal water weighs about 530lbs. Might make a difference if the tank is all the way forward or rearward. And hope that Keystone put the proper support irons under the tank...have read of several instances of the tanks falling out due to improper location/insufficient amount of supporting braces.
I travel with 100 gal quite a lot when headed off to dry camp, but my water tank is in the middle near the axles. Doesn't change the traveling dynamics and I don't notice any mileage difference, tho surely there is some damage to mpg.
Joe
