I feel like a real idiot having to ask this, but there is a lot of "discussion" going on here about what size our propane tanks are!

A quick Google search turned up this Keystone Hideout Specifications Page which indicates your trailer came with two 30 lb tanks.

30 lb is about 7 gallons. Watch the meter or review your receipt next time you fill.
Your local propane dealer can confirm by glancing out his office window.

Thank you! Appreciate the help and the direction. Off to tell DH he was wrong! LOL!!!

If you figure the normal gas grill tank is 20 lbs, your tanks should be taller. I actually have 2-20 lbs tanks on my trailer.

Go to your propane filling station and ask the tech to explain the WC, TW and date # s on your bottles collar.
wikipedia has a fine description of the properties of propane and its safe handling.
For instance, a WC of 72 is the water capacity of the bottle expressed in pounds, so correllated to propane 80% fill level at propanes 4.24# / gallon weight, that equals 30# propane. On a temperature compensated meter it works out to about 7.3 gal. propane in 30 # of propane, 4.7 for 20#, 23.56gal. in a 100# bottle, and so on.
Know the math and properties to be certain you get safe filling and your moneys worth, and that the filling tech does also.

Just FYI---what you have are propane CYLINDERS. They are not permanently attached to the RV, and are designed to be moved around and shipped in the commercial transportation system.

A propane TANK is fixed to the RV and is generally not portable or intended be frequently removed.

The distinction is important, because the inspection requirements are different.

Cylinders need periodic inspections and recertification by a qualified US DOT-trained inspector. (These are pretty common, not hard to find.) DOT inspection requirements, and list of qualified inspectors.

Tanks are manufactured to standards set by ASME (American Society of Mechanical Engineers) and are not required to be re-certified. Of course it's a good idea to give your tank and valves a thorough look to check for excessive rust or damaged fittings.

YEAH!!!

Somebody that gets it and understands the distinctions and reasons for the correct nomenclature :B :B

YEAH!!!

However the original poster didn't need a lecture on the correct nomenclature. :R

Everyone understood what TheBeans was asking and replied with the helpful information he was looking for. ;)
