Our NorthStar came with one horizontal tank, that can also be used vertically (the gauge is read two different ways depending on the orientation of the bottle). It can only be used in the NorthStar horizontally. I'd like to have a second one. Couldn't fine it at Camping World, Amazon, or at several Hardware chains. Anybody familiar with these and where they're available at?

Never seen a 'dual' use propane cylinderHorizontal propane cylinders for RVs are placed in 'service' when laying down and 'filled' when standing up so the OPD functionsThey shouldn't be placed in service when in Vertical PositionRelief Valve would be submerged in liquid propane vs vapor and if it OPENS Liquid Propane would be spewed out. That can be VERY dangerousCall/Inquire with NorthStarTel: (319) 233-3461

What size? I see both 20 and 30 lb Manchester horizontal LP tanks on Amazon.Not cheap, but they have them. I replaced the two 30 lb horizontal tanks in my TC last year. Still ouching from that one. :):)

time2roll gave you good link and internet usually has better prices. If you are in big hurry, or want to touch the item before paying -call local propane distributors. I used "Suburban Propane" and their main location had several models of propane CYLINDERS.

I just ordered one from here. $175.10 with free shipping. Best price I could find. It took several weeks to get.http://www.propanetankstore.com/20-lbs-5-gallon-manchester-horizontal-propane-tank-with-gauge/FYI, Canada requires tanks be re-certified after 10 years vs 12 years here in the states. I wanted at least one new one for our Alaska trip.

Strange as the link shows CYLINDERS.

Cylinder is what OP is looking for. (Tanks used in MHs)

They're calling it a cylinder but it's a tank, Plus the site isn't working so probably best to contact them

Ok, thanks. So the vertical reading part of the gauge is for filling only; I didn't know that. I'll check Amazon again; I must have missed it.

20# Horizontal Cylinder---$172

"This 20 lb steel horizontal propane tank holds roughly 4.7 gallons. This tank is to be used in its horizontal position only yet filled in a vertical position. This tank is equipped with an OPD device and a gauge."

Another one.....again Vertical for filling ONLY

Forklift CYLINDERS are 8 gallons and have big fill valve (no overfill valve), while RV 7 gallons cylinders use service valve for filling.
I think you could use them vertically, but they are design to work horizontally and vertical scale is not very accurate.

I have been around a lot of forklifts and I have never seen a truck camper style tank on one. The only thing they have in common is they both use horizontal mounted tanks.

I think those are the same type of tanks used by industrial equipment like forklifts, try a supplier or repair shop that works on them.
