Tips to pull dry and have water later

First off, I wanted to make it clear that our family is supper new to this world and have received a crash course of sorts to get where we are now. We purchased a Forest River Sierra 27 ft Toy Hauler. We are supper excited! we noticed that we have two very large water tanks under the trailer and have two questions:
1) average toy hauler is around 100 gal but the dealer was under the impression our tanks looked "bigger" than normal. How can we know exactly how much water we are packing? This will help with the weight calculation.
2) Driving any amount of med to long distance with around 700 lbs of water can eat fuel. What can we do to leave empty but fill up near where we plan to dry camp? Are there places to fill up? And how can we locate them? Are some places better than others?

Again, Thx in advance

Welcome to "The World"!

I believe you should have a "Cargo Carrying Capacity" sticker on the RV (front drivers side exterior?). It might not mention how many gallons, but it should mention how much a full load of water weighs and you can do the math (8.3lb/gal according to my sticker).

Alternatively, you can check the manufacturers website for the specs of your camper.

Sorry, I don't do much dry camping, so I can't help you with where to get water while "on the road".

First, it would help if you posted year and model number.
then someone might know where to find the info you need.

Second, an extra 700lbs isn't going to lower your gas mileage much, since it's the trailer's frontal area that affects mpg more than weight.

Third, where do you plan on dry camping? every campground we've dry camped at, had potable water available at the dump station.
or do you mean that you plan on boondocking?

I attached the sticker from the front driver side but do not see the water weight as suggested. I had a thought of Turing on the hose and filling a 5 gal bucket, timing it and then seeing how long it took to fill the tanks. That math would get me close.

I thought dry camp was out with no facilities, but again I am new to this world and lingo. If this is called the other, then yes that. We plan to go to Moab soon and its a 4 Hr pull. I would rather pull dry than wet if possible but would not know where to fill up down there if not staying at a campground of some sort. IE KOA

I have a ton of questions like solar, batteries, LED's location finders which makes my mind swirl... But I am creating new threads in the proper areas. 😉

During our early travels, we bought the idea that hauling water from home wasn't a good idea. We found an awful lot of really skanky water out there. Our home town water ranks among the top 5 in the nation for quality and clarity.

Our rig had a 45 gallon tank, so I figured an extra 400 pounds or so in a 22,000 GVW rig wasn't going to make that much difference to gas mileage and it was well worth it for the quality. A Dan points out, our vehicles aren't the most aerodynamically efficient out there!

Most of the places we camp are dry in the sense that while there ~may~ be a water spigot for washing dishes, there's no electric or water hookup; the toilets are one-holers. There is no dump station, so no opportunity to get water. (We mostly go to Forest Service or state campgrounds.) We just fill our tanks before we go, but we might be able to fill up at a gas station before we head onto the dirt roads. Never even thought about it before, so don't know for sure if it's doable!

In PA, the state park campgrounds, at least the ones I'm familiar with, have dump and water fill stations that you can use even if you aren't camping at the park. Our local state park charges $9 to use the dump station. You can try finding a state park near where you want to go.

When we bought our new camper it was recommended to us by the dealer not to travel with the water tanks full as it puts undue pressure on the straps holding the tanks. I don't know if this is true or not, but we always stay at campgrounds with fresh water hookups, so don't haul water anyway.

And they do make in-line filters for RVs to help clean up any taste, color or clarity issues with water supplied by the campgrounds.

Agree that the full FW tanks won't impact on fuel mileage much.

The location of the tank(s) can be very important and the impact on tongue weight.
