Who tows with full tanks?

I have a 2011 26BH and I always thought it wasn't smart/safe to tow with a full drinking water tank. What are your thoughts? I am driving cross country next week, so I am curious.

I will seldom have the FW tank full but will always have 5 to 10 gallons for personal use during the trip. If the trip is short it may only be the 5 gallons for a couple of flushes if needed.

If bringing G'kids I may need more.

Generally I keep about 5-10 gallons in the tank all the time just in case I need some water en-route for some reason. If I know I am not going to have hook ups at my destination I will fill the tank at home. I KNOW the quality of water here. I do not have much confidence in what you might get a truck stop just prior to your destination. However, the distance I am going to travel may alter this.

On another note: ALWAYS fill your fresh water tank from a filter. Small particulants (ie: that stuff that accumulates around your shower head at the house) that may get in without the filter can be a problem with the valves in RV plumbing.

I almost always travel with a full fw tank. Most of the campgrounds around here have a really high iron content in their water and I prefer my 'city' water better. The only time I travel with full or nearly full black and gray tanks is if the line at the campground dump station is too long. There is a dump station near my house that seldom has a line.

I also keep about 5 to 10 gallons of fw in the tank but I always dump my blk and grey tanks because they are behind my axles and it just ads to trailer sway. Empty tanks no problem.

We only fill the fw tank if we are going to a local CG. We have an 86 gal tank & don't want to pull that extra weight too far.

I regularly tow with a full fresh water tank.

Often, the gray and black are nearly full while towing. I prefer to dump the tanks upon arrival at a campground. There is never a line on Friday. Plus, the motion beaks up the "stuff".

I've towed over 50,000 miles. I keep meticulous fuel records. I have found my fuel economy is not affected by having fluids in the tanks.

Depends. (Considering....for us we camp 99% with full hookups, so we don't have to worry about water or waiting in line for dumping). But for most part we have less than 1/3 of a tank when heading to a full hookup campground. Long distance travel we will have less but enough if we plan to 'boondock' at a WM/etc. When we do full day drives, we usually spend a few days at c/g before doing the next full day drive so it's no biggie for us to hook up the water

We empty our blk/grey before breaking camp. Occasionally we add ice with the little "clean" water that remains in the black tank to help with cleaning while driving down the road. We always add a few drops of dish liquid.

With our current tv, we do see about a 1/2 mpg difference when towing with less water. We also feel a slight difference when towing with all tanks full (we have a 1/2 ton).

Our home water isn't the greatest (and most c/g's) so no matter, we bring a couple of gallons of bottled water for coffee/cooking.

Are you traveling to 'sight-see' and is the whole family going along? We spent three summers with our kids years ago seeing the lower 48. Great memories! Have fun!

I pull with full tank for 2 reasons. First, it actually rides better. Second, some of my family has sensitive skin and prefer's a "home" shower.

I'm with the "few gallons just in case" crowd. Mainly for en route flushes.
