Earlier this year a purchased a new to me 2007 Nimbus. In the specs it states it's fresh water capacity is 95 gallons. My old country coach had 100 gallon and my wife and I were able to last a week approximately on that. The Foretravel is about 4 days. I know that two areas of concern that I've dealt with are the shower and toilet, as it is electric flush. However, as of today I purchased a gallon meter for garden hose. I calibrated manually against a 5 gallon bucket and it shows 4.6 gallons to the 5. Then I filled my completely empty tank and it hit the overflow at 72 gallons. That puts me roughly 20 gallon short. To be sure I then put the meter on the outside faucet and pumped the tank empty and it produced 73 gallons. To be sure I opened the tank drain and got another two gallons. Has anyone heard of anything related to the capacity of the 2007 nimbus? Is there an issue with the overflow location? Would love to hear any feedback.
Thanks.

Foretravel was in trouble back then. Possible they only had a smaller tank available to build this coach.
Maybe FOT has a correct tank?
FWIW, my 2003 U295 water tank is supposed to be 112 gallons. I have used an inline gallon meter, and found an empty tank overflows at 85 gallons. Either the Chinese meter is in accurate but repeatable, or FT never knew how to calculate or measure tank capacity.
Sounds like auto shutoff stops too early. Coaches without auto shutoff just fill until we manually stop. We can see the inside of our water tank, but if one forgets or cannot see their tank, we know when full when tank starts to overflow to ground. Why not temporarily bypass automatic shutoff and redo your measurements?
Mine has no auto shutoff, just overflows.
On my 2007 Nimbus, we experience the same problem. The tank actually is about 75 gallons which I was able to see myself when we removed the tanks to thermal wrap them. As for the overflow, that is simply a fancy valve on the top of the tank. There is no means to vent the overflow water other than allowing in to flow on top of the tank and flood the compartment which I have done more than once. So, 75 gallons is the true limit of fresh water.

Tom's note is a reminder that if the coach has not had its overflow hose rerouted, overflowing out the rear bulkhead hole on to the bottom bulkhead is a no-no, as it will keep the bulkhead wet and wanting to rust. And if before leaving campground, even if we stop filling before overflowing, coach turns will tend to spill a near-full tank contents on to the bulkhead. The only answer is to re-route the overflow hose. In Bob & Kathy's coach, I am surprised that the overflow is intended to spill into the coach compartment, and wonder if a hose to the outside is missing.
I think I need to reroute the overflow. Anyone have links to how this is properly done?
Try typing "fresh water overflow" into the search box - you'll get 6 pages of relevant hits.
I can't believe Foretravel doesn't have an "overboard" overflow on these later coaches. My tank is suppose to be 102 gallons. When I had it out I measured it and created a CAD model. Looking at it now it calculates out to 101.5 but that is with sharp corners and no consideration for wall thickness. Guessing 1.5" from the bottom to where the top of the suction line is, that calculates out to only 4.5 gallons of "unusable" water. I don't see how there could be such a large discrepancy; unless your model had a uniquely different tank.
Many years between my 1991 and 2007 and I'm really not sure how different it might be. Mine OEM setup had an overflow onto the rear bulkhead and just a manual valve you had to babysit. I also didn't like the spillover when making left turns. The spilling on the bulkhead isn't too bad if the joint between the heavy angle and vertical sheet metal is sealed with a good polyurethane caulk that will last for years and years. So, for what is worth, here's how I re-routed mine: Bulkhead Repair (Partial Floor Replacement) (http://www.foreforums.com/index.php?topic=31694.msg280570#msg280570)
FYI, we measured all dimensions of our tank from the outside of the tank including the slope, and then shortened measurements to compensate for wall thickness. And then computed capacity from these measurements with water level at each 2 inches up the tank. With our lamp on top of tank we can see water level through our translucent tank.
Bobnkathy was there room for a bigger tank?
There was room for a bigger tank inside the area but how to get it through the door opening would be the question.

Ugly. Next compartment a sister tank plumbed to fill and drain at the same time? 75 would be a deal breaker for us,
Old ftx had 75 up front and was not enough for dry camping and dishes.
Would have to switch to throw away plates and such to extend the use,
Or pump more water into the tank from a non plumbed tank in another compartment?
