Harv,
The BF you have has a freshwater tank that is built in L shape. Although the tank is fairly solid it has a weak point on the inside corner. My buddy got a crack in this corner and had to take out the tank and reseal it. If you want to blow out your water tank keep this in mind. I usually just drain the water tank as I park the truck on a steep slope the water drains not only from the tank but the drain line leading to the rear of the camper.
I wouldn't chance a pressure any higher than 3-4 psi. I must say it is not quiet clear what caused the failure but it may have been from filling the fresh water tank. I recall Brad has a pretty high water pressure, over 50 psi.
Larry.
Draining the rest of the plumbing you're probably OK with 40 psi, but a lower pressure will do the job as well.
I went out this afternoon and bought a tire inflator chuck for about $5. I had to shave the end of the plastic blow out plug so that the chuck would go in deeper and stay on tight. Works nice.
Alright!!! one of the solutions with pictures even.
Glad the shaving of the plastic Camco plug worked for you. With the brass Camco all connects easily. The home made blow plug devices are a great way to go but some guys/gals may just not want to bother but just buy a Camco or similar valve. They all get the job done fortunately. 8-)

Thanks for the info Larry. My driveway is on a slope, so I just have to swing the truck around to drain the tank. BTW, how would you blow out the fresh water tank? Just blow air in from the fill line?

I have a fill line that goes back around the water pump. When I open it, water can go from the pressurized system back to the tank.
It also works to let air into the tank and blow it out the drain line. If I open it too far, it will just pop the gravity fill open.
I went to home depot and bought a brass male garden hose to 1/2 female NPT bushing. I then threaded on a 1/2 to 1/4 bushing and finally a quick connect air coupling that fits on the end of my air compressor hose. I can put more air through that than a schrader valve lets through.
how many dollars was that? instead of the $1.59 ready made jobby? the last time I bought brass fittings at Lowe's it cost a fortune. and I'm going to check your math the next time in there.

Do I get to count the gas? I can walk to Home Depot at lunch time. If I want to go to an RV place, it's a 30 mile drive - if they have it. Camping World is 65 miles, one way.
To me it boils down to the low-flow going through the valve. I plug it in, open up the line, and I am nearly instantly pressurized. It's not a cost thing it's an effectiveness thing. If someone makes a plastic, one-piece hose inlet to NPT inlet, I'll go buy it. Otherwise, even though I have one that works, I'll go buy a slighty shorter set of adaptors to avoid taking my blocks out.
Of course, if you are worried about wieght you do probably shave a few ounces with the plastic!
