My wife has been researching TT in anticipation of buying a new one and came across an interesting comment. A fellow camper was traveling with a full water tank and at some point on the journey, the tank fell off while driving. When they contacted the manufacturer they were told it is not covered under warranty. Further, they were told that the warranty specifically warns against this practice. I know we travel with a full tank (30 gallons)if we know there is no hookup where we are going and after reading the forums for some time it appears to be a common practice. Any of you folks heard about this or had any experience with a self ejecting tank?

That would be real hard on my unit as the tank is built into the basement above the lower floor. I callB.S.

I think you have just learned that not all claims made on the Internet are completely factual. :)

I,ve heard of tanks falling out ,just plain poor quality workmanship. they could do a hole lot of damage .my guess thats why no warrenty .

Hmmmmmm, a lot depends on the manufactur. My old Alpenlite had a 100 gallon fresh tank. We usually traveled cross country with it at least 1/2 to 3/4 full. We traveled for a couple hours local with it totally full and never ever had a problem with any of our tanks. Now with our Montana the tanks appear to be fairly weak. We have read where they will burst and drop too. In fact I over filled my galley tank it it burst to where they had to replace it. The fresh tank is only 60 gal I think and we still travel with it 1/4-1/2 filled and so far so good on it.....Oh and my extended warranty did replace my galley tank..

Water weighs about 8 lbs/gal so the tanks do get heavy- and when you hit a hump or a bump that weight can multiply. But still, what good is a tank if you can't haul anything in it? I did have trouble with my tank (poor design) but I put extra support under it so I can haul a full tank now. How can you go camping if you can't take water with you?

I take a little in the tank for enroute uses and then fill up at or near my destination.

I think the bigger problem is if the tank is half full and it starts sloshing around and that weight (8.3 pounds per gallon) is sufficient to damage the tank and supports. A full tank should not be that much of an issue unless perhaps on a very bumpy road. Shame on any manufacturer that cannot make a tank support that supports the tank when full.

We rarely have more than just a very few gallons in our tank for just a couple of reasons...we always camp with water to the site and the other reason is that water weighs 8.3# per gallon, which is a lot of weight to haul around and decrease already poor mpg.

That story sounds a bit "old wives tale" or vivid imagination, but also sounds like it COULD be possible under the right conditions. If you know you're going to need FW, suggest you wait until you're actually at the CG and use their potable water supply on the way in.

I normally travel with the FW tank full as we do a lot of camping without hook ups. So far about 15K miles without issue.

When they did the PDI on our new trailer, they said not to travel with a full tank of fresh water because it wasn't designed to be hauled full. Not a big deal to me as I've never traveled with a full tank of fresh water and most of the times, our tank is empty.

Don't shoot the messenger, just passing on what we were told.
