To travel with Full Water Tank

[aufinger]

[QUOTE=Hutch333id;1605077] Take from that, the combined weight of all your passenger, fuel, hitch and anything else your place in the truck and then the hitch weight of your trailer, ..... QUOTE]

Toyota includes the weight of fuel in the vehicle's curb weight so you don't need to deduct it from the cargo capacity on the door sticker. That being said, if you weigh your truck, you should have a full tank of gas.

There's no way a Tundra has a payload capacity of 2080, that is unless you remove the truck bed. Larry G.

Overfill the tank ? They have overflow lines that prevent that from happening. Unless you physically plugged that line, you can't overfill.

[Jeff_and_Abby]

What happens to some, is either the volume of incoming water is greater than the vent can accomodate, or the vent may be plugged ...

In any case the fresh tank acts like a big bladder and expands under the hydraulic pressure. Think about mud-jacking concrete ... liquid under pressure can exert a LOT of force. Come to think of it, isn't one of the methods used to form sheet steel, called Hydro-Forming ??? At any rate ... that is a way that damage can happen.

Not saying that several hundred pounds suspended ... possibly sloshing around ... and some G-force from thumps and bumps ...

Just not something you want to discover on the destination side of your trip.

You might just crawl under your tow and look at your water tank paying particular attention to the support system for the tank. May just alleviate any worries/doubts that have been created. They have fallen out but most don't.

Tow all the time with full tank. Also have a 20gal drum in back of TV . Can gravity feed into tank on TT. Also can go get water without moving TT.

I travel with a full tank all the time with no issue. Not only does it provide water on the road, it provides a bit more tongue weight to help keep sway in check.

Have a sunseeker 2860 and have never not left home with a full tank and a lot of cargo. Isn't that the whole reason you have a motor home or TT? Sometimes pulling a HD trailer with UTV and no problems

[Maxwell D Pratt]

I travel with my tank full all the time. Also carry a 20 gal tank in back of truck. To some places.

We have a Wildcat 29RKP and TV is a GMC Denali 3500 SRW Crew Cab. We have never hauled with more than half a tank ( 30 gallons ) . Good thing. Had work done last week and when they pulled the belly liner off it showed the freshwater tank had one of the three straps broken ( the screw missed the frame when installed ) We now carry a 65 gallon fresh water tank behind the hitch in the bed of the truck. Works great so we can always pick up fresh water when we see it and then put it into the rig for a later time. We are always mindful of the extra weight though.

I don't want to get too far off topic but what is the difference between Payload and VCW? I haven't heard the term VCW nor seen it in any of my Ford literature.

Edit: quick bit of math - maybe the weight of the fuel deducted?

Just bought a brand new Vibe and our dealer recommended that we do not travel with a full water tank!

I always travel with 64 gallons of FW. Asked the service mgr about that and his comment was "why not? That's what it is there for".

We have an eight hour drive. Will a full water tank effect safety, travel trailer structure, or MPG?

I've seen a stronger consensus towards No, but still worry a bit.

I only travel with full tanks if I can't find a Loves or Flying J on the route. They offer fresh water at some locations. I call ahead to verify they have it there an then I fill up when I get close to my destination. Saves on gas mileage.

The answer really depends on personal experiences and feelings about the subject.

Those who have had problems with a full fresh water tank not being supported properly, or who believe they are at the margins on weight already, do not want to travel with a full water tank.

Those who camp in areas where good fresh water is scarce want that water tank full in advance.

There are certainly many cases where the camper was built with insufficient support for a full water tank traveling over not-very-good roads. This can be fixed with some work, but for folks that don't need to travel with full water tank - why bother?

At the other extreme, my A-frames tow and ride better with a full water tank. Tank is just behind the axle, so the extra weight helps a tongue-heavy situation. I'm considerably under max gross, so the extra weight helps the suspension ride a little more softly.

just my thoughts and experiences

Theoretically, your water tank supports are strong enough for a full tank, but we've all heard those stories. The extra weight will affect your handling in some manner. If your tank is way behind the axles, your hitch weight might be too light, or the opposite if located forward. Extra weight means decreased fuel mileage, but I doubt it's a lot. You may have to adjust your WDH accordingly. I rarely boon-dock and never travel with water unless my destination has none.

If my fresh water tank is too full...and water starts to exit the over-flow tube...it will create a siphon that will all but empty the tank. This happens on inclines or declines that forces water with volume into the tube. Next step is to add a valve to prevent this on long trips where I know water source is hard to find.

I put a rubber stopper in my overflow to prevent the siphoning.
