Min. black tank for 7 day Boondock?
We have a short list of sub 28' "couples" trailers that we are considering. Some have black tanks as small as 25 gal. What is a min. tank size, for a couple, that would allow us to boondock at least...

First.. Most RVs listed capacity is not accurate.
They usually fall short of the stated capacity.
One of the first things I do with a new RV is to actually measure it, and log just how many gallons are in the tank for each light on the monitor. Then I can tell just how we are doing when camping. I have had 3 new RVs. My present one is the only one that held as much as the specs stated... My Momentum has very large tanks, and actually holds more than stated. With this one I no longer have tank anxiety. We recently were on a 3 week boondock hunting trip, and could have gone longer. Had FW to spare, and room in all tanks. I think we can do 4 weeks now.
On my previous RVs, Black was always the limiting factor... Getting more Fresh is easy. Getting rid of grey is as well.
My advice to the OP? since you are asking about boondocking, get the biggest tanks you can... And Grand Design seems to have good sized tanks that actually hold what they are supposed to.
