placement of fresh water tanks

any thoughts on whether 100 gallons of water is heavy enough to make me have to place the tanks in center of the bus as to keep it from being over weighted on one side. i would like to put them off to one side in the rear bedroom, just dont want to cause trouble if it will be to heavy to not be centered.

Tango brought it up in an earlier post- 100 gallons of water is around 850lbs. Definitely centerline it along with your grey tank. We RE owners have the advantage of empty space between the frame rails. My plan is fuel tank, fresh water then grey

you going to run them between the frame inside the basement? that was my plan for black and grey, but i hadn't considered fresh there to. i am liking the placement so well where i have them in rear bedroom i debating if i could just block up rear of bus when we stationary to keep all right in the weight bearing world... gonna have to think on this before i get them solid down. that today's plan is rear bedroom framing so i will let ya know how it turns out. thanks for the intel as always scooter

Remember, the further under you place it, the harder your pump will have to work to get it up to your sinks and shower.

I was wondering if you could use 2 pumps of the same size to get better pressure to the shower or sink.
One at the tank to get it started, then the other closer to where it will be used.

My only concern with placing the fresh supply under the belly is freezing. Unless the tank is extremely well insulated or has an electric heating option added, you are limited to staying in warmer climes. As long as that consideration is taken into account, it should be fine. Without it, you wind up with either no water or a busted tank.

Just something to keep in mind.

2 pumps = overkill and excessive battery drain (if you use 12v pumps.)

An accumulator tank would be fine, the pump primes it and then it doesn't have to try to re-prime the line. However, if your tank is underneath, your pump will have to do 1 of 2 things, either pull the water from a further source, or if the pump is close to the tank it will have to push the water up. Either way it has more wear on the pump itself. If the water storage tank is in the same level as the pump and faucets/toilets, it doesn't need to work as hard and you wouldn't need an accumulator tank.

Doesn't anybody use hand pumps? I'm not talking about a cast iron pitcher pump stuck in a barrel. Years ago I met an old guy that used a hand powered bilge pump, ordered new of course so it's clean. It will draw from a maximum of 3 meters below the pump according to its specs.

Also, how much difference does its forward position make relative to the ride of the vehicle/stress on the chassis? Better to have rear or mid cabin? Just curious!

Here's how Vonslatt plumbed his bus. Which is how, for the most part, mine will be (when I get there)

These are medium duty truck frames. It shouldn't stress out the chassis too much, and keeping it just aft of the fuel tank (at least on an RE IC Bus) shouldn't keep you from overloading the front wheels
