I don't have any specs for a 75, but for a 1974 D21 brave, the 1974 Winnebago Service Manual lists the wtr tank cap as 30/60. I don't know if the 74 is the same as yours, I guess it might be. It also says the curb wt is 7,920, the GVWR is 11,000, that it has a 125 inch wheelbase, a 36 gal. fuel tank, that holding tank #1 is 21 gallons, and holding tank #2 is n/a.
As far as I know the Winnebago Service Manual first came out in 1974, and I haven't seen any other edition of it. Mine is edition sm-1000. Does anyone know of different editions? denison

The winnebago owners manual for my 76 D23 Chieftain lists 60 Gallons - I actually have 2 Galvinized tanks under the rear Gaucho ( in the rear storage Compartment ) I lists 2 - 25 gal tanks for the D26RK model maybe thats the tanks installed on mine - otherwise they are 2 -30 gal .       Sea Hag

This is a Brave D21 Special and I have 2 fuel tanks without a change-over switch that I  don't know the capacity of. I have 2 fresh water tanks that I don't know the capacity of  and a black and grey water holding tank that I don't know the capacity of.

They used the same size fresh water tanks in many models as well as fuel tanks . If your Fresh Water tanks are like the ones I described in my 76 D23C they may be the same size . For a complete list of capasities for your D21 you might get an owners manual avialible from winnebago dealers - I think there is a list of them under manuals on the boards . that is where the info came from for my 76 they are really helpfull and have all of the capasiteis listed as well as operation of the systems . providing a PO did not change things - Sea Hag

I have the orig. owners manual that came with the MH but the specs listed in it are for a (20' and a 24'). It specifies one 25 gal water tank and I have 2 tanks. It says that the fuel tanks are the same in both ( 36 and 20 gal.)<----might be correct.  The information doesn't seem to jive with what I see when I look at the MH  I would compare it with the 20' but the 440 in mine isn't even an option in the 20'. this is a pic from the manual. It appears to be a later model but has 75 Brave on cover of manual.

Yes the owners manuals sometimes does't match what is there the location of the tanks are not where it shows them on mine they are somtimes rather genaric - I think you could order pretty much what you wanted . and being a Brave Special  it may have been somesort of package or built for a show or worlds fair like the Expo model  - They also used different methods for pressurized system with air pumps and various water Pumping systems - are they galvinzed water tanks ? - Sea Hag

The tanks are galvanized. Lots of things are different on this one. When I spoke with the guy in Iowa about the fuel tanks not having a change over switch , he told me that that feature was on the EXPO model.

When I see you next summer, remind me to show you the 2 galvanized fresh water tanks in my Winne.

Well talking with you guys I am sure that I will find out more about the MH a little bit at a time.

Rick - My 76 D23C has two fresh water galvinized tanks as well - I think they used them for a pressureized water system as the switch for mine say's compressor - They pressurized the system with air from a compressor for water delivery when camping self contained and used the pressure from city water regulateed through the water fill valve when docked . Iv'e read in other disscussions that the galvinzed tanks are glass lined like a water heater - but haven't confirmed that yet on mine - other than the water is not rusty . Mine has been converted to a surflow on demand water pump - I'll post some pics next time I go down to work on it - Too cold right now -I plan to remove one to make extra room and lighten up the rear of my rig .
        Big rock - from my owners manual I think they are 25 or 30 Gal. Each . There was also a disscussion a while back about the auto switch over fuel tanks on the Expo - no one had heard of it before but it does exist , don't know if it works - I guess you'll find out . Hang in there we all learn bits at a time --- Sea Hag

My owners manual lists operation of both demand pump and air compressor The way it is set up I think it was originally an air compressor - When it warms up , Hope that is soon but not likley have to wait for the groud hog to poke  its head out . You will find that when you fill it up you need to open the relief valve next to the fill . If your manual does't have the prosedure I can send you a copy Via Email --- Sea Hag

Just a quick note to confuse this all the more! My  72 C-20 Brave also has two fuel tanks, and two freshwater tanks, and of course a Blackwater tank, but no Grey water tanks since it was not considered necessary back then. The two Galvanized Freshwater used to run on a compressor, but now have been retrofitted with a demand pump. The Two Fuel tanks hold 29 and 23 gallons respectivly.
Just thought I would stir the pot a bit.

We used to stir the pot so it would burn better  - Anonysob
