Does anyone know how large the original LP tank was on the 73? At some point for safety I'd like to replace it. But just curious how big it is. The plate had been painted over several times on mine.

The LP tanks that are installed in our coaches are ASME code tanks and
are not subject to the DOT regs that require the newer fill valve and
inspections. If you want to do anything just remove the tank wire
bush and clean it up and repaint it and reinstall it. You will have
less problems down the road. It should be 42" long and holds 62
pounds of propane. The real problems that you can have with your LP
system most of the time is the regulator and it can fail after all
these years. It should be set for 11 "H2O for proper operation of the
furnace, frig and stove.

The LP tank on a 23' is 40 lb. I don`t know the dimensions off hand, but I`ll be at the barn tomorrow and can measure it for you if you need??

I have some problem trying to read the plate on my original
propane tank in my 23 foot 73 as it is rusted some and
probably was never stamped deep enough. What I can
read with a flash light is:
Brunner Eng & Mfg.
Bedford, IN.
Above ground only
Max WP 512 PSI @ 300 DEG.
Gal. 13.4 MFG. SN. U294
??? wt 65 pounds
I tried to measure length and diameter with a tape measure.
Length looks like 26 inches diameter aprox 12 inches.

The 13.4 gallon capacity is liquid full. Actual useable volume is
about 11.2 gallons+/- at the liquid full vent port. Wire brush it up
and repaint and your good to go. You may want to test the regulator.
One thing that I would do is mark the fill for your water tank as
Potable Water Fill with a small sign. One GMCer had it filled with
gas by a helpful repair shop. True story!!!

I pulled my original tank and use a regular 5 gal tank that I can exchange almost anywhere. Gained the storage. Yeah I know you guys that camp for extended periods think you need the extra capacity but I have not had any issues with the 5 gal.

Michael,
Did you get all the info you needed on the propane tank?
Do I need to go out in the day light and see if I can read more info?

The standard LPG tank on a 1973 26' was a 44.5lbs tank. Option # UNE was a 62 lbs tank for $25 extra and "might" be listed on your glove box sticker.

I have an "emergency" one gal tank that I use as a back up in case someone forgets to fill the 5 gal tank. As Arch would say "works for me'. Envey you "hanging out" in the southwest for the winter

Randall, when we are parked for a month or so I use 2 rv tanks instead of the onboard tank. That way I dont have to move the GMC for gas.

The propane tank on my GMC MH was 62 lb. A previous owner penciled in 7 3/4 gal in my operators manual?? When I got the coach, the seller gave me a new outlet valve. The valve on the tank leaked when opening or closing it. I also later found that the filler valve leaks. I took out the tank and use 2 20lb barbeque tanks for my first trip, had to cutaway the insulating foam to get the tank that is attached to the regulator to stand up and fit in the tank space.
I had planned to glass bead the 62 lb tank and repaint it, then get it cleaned inside,valves replaced, and re-certified. The major propane dealer here refused to look at it because it was for a RV and I had removed it from the RV. They refered me to another dealer who wanted over $250 to do the above.
The forklift shop where I work had a never used 40lb tank they had got by new by mistake and could not sell. I got the tank for $100. I took it to a propane place and got the outlet valve change from liquid to vapor with-drawal, flushed, re-certified (the shop had had it for 7 years and there was only 3 yrs. left) and filled for an additional $50. I told the propane place where I got the work done and filled that it was for a forklift, I had a feeling that if I had mensioned "RV" it would have cost a lot more. I will have to make a latching type mount for it because I suppect that although the tank has a filler valve it will have to remove from the coach to fill. Also the tank does not have a sender for the remote electric guage in the coach.

I know that you are not using it, however, I just wanted to point out that since they are ASME tanks, our GMC motorhome propane tanks never need recertification.

Thanks Emery
Am not sure what the regs are in Canada. Should have recearched same. Thanks. Did check Wikipedia and found propane weighs approx 4.2 lb per US gal at 60 f. So 62 lb is 14 3/4 us gal

Again thanks Emery
An added note:
The main reason I wanted re-certified is that I understand part of the re-certification is that it is filled with liquid and hydrostatic tested at a higher pressure than it is used at. I don't think it would be very pleasent if one ruptured with propane in it. If I did think of using it I would do a very carefull inspection of the inside.

Well it looks like I have the 13.4 tank. I'm on the second dual stage regulator in a few weeks. The first one was defective. The rv center warrantied it.
Then I tested out the new one they just installed and it to is defective!
Well I called them and they said they are getting in a new type tomarrow. So weds I have a appoint to get it replaced yet again, and they are going to get the carb on the generator just to make sure its running fine.

Just curious, do we have to wait till the tank is empty to refill or can it be refilled with gas already in it? 2.5 years with my rig and just now down to 1/4 tank...
