Hello Trailmanor Owners,
I would like to replace my propane tanks. I have a 2003 TM, 2720 SD. The tanks are HORIZONTAL and appear to be 5 gallon, because they look like BBQ tanks of that size.
TM “Datacard” just gives a generic number for Manchester tanks, but not gallons/pounds.
Does anyone know the actual gallon/ pounds of the original tanks?
Thanks for any help.

It is the same as a standard upright BBQ tank - 20 pounds nominal. Be prepared for sticker shock on new ones. You can have tanks re-certified by an actual propane dealer. You may have to look around to find one.
 
Thanks again, Bill. You’re right about checking for re-certification.
I found a dealer and hopefully re-cert price comes in lower than new!
I think I found a tank online, as well, Flame King YSN201HZL 20 lb. for $104.
I’m prepping trailer for sale and don’t want to pass on problems. Then I’m donating the proceeds to a good charity. Your help indirectly helps them!
 
I purchased the below tanks. I was unable to find anyone that "recertifies" portable tanks anymore. However........... I found out (too late) that some places will replace the OPD valve and that includes inspection and certification. I never checked on the cost.

 
I've gotten my horizontal tanks recertified before at a major propane distributor. Think a place like AmeriGas where there are huge tanks on site with tractor trailers or other large trucks of propane go in and out of.

A new valve was about $25 (which had to be reordered as it apparently is different than that used on a vertical tank), re-certification about $15, so still cheaper than buying new if the tank is otherwise in good shape. Don't think though that a re-cert involves any real inspection. They basically looked it over to make sure it didn't have any holes. :ROFLMAO:

I only replaced the valve because it was leaking around the valve stem, and re-cert lasts 5 years I believe.

Thanks Wavery! That’s the one I saw online as well. A TM owner even reviewed it so it should/ may/ otta work on other TMs as well.

Hi Dave,
I was able to get a 5 year re-certification at Blue Star Gas here in Northern CA. The damage was a mere $20 per tank. You’re right. They applied pressure with the fill nozzle. They didn’t see/smell/hear a leak, so I was good to go. It seems like replacing the valve is a smart move, especially since my tanks are original to my 2003. Next time.
Thank you, Kermit
 
Indeed I think replacing the valves at each re-cert (or maybe every 10 years, so definitely at the first recert) is wise. The alternative is that you notice you have a leaky valve when you have a full tank, and then you can't use the gas because of the leak. And you can't replace the valve till the tank is empty. So you end up taking it to the dealer where they just vent the tank into the atmosphere to replace the valve. Not only bad for the environment, but the money wasted on that propane would pay for a new valve....
