Change to 40# LP Tanks?

[JayleNBob]

I'm considering upgrading to twin 40lb LP tanks, has anybody out there done this? If so, will they fit inside the OEM LP tank cover without any modifications?

Any insights are greatly appreciated.

Thanks!

They're taller so they will need a cover made for 40# tanks. You might also need to change the hold down clamp to accommodate the taller tanks. Mine will only hold 30's, or 20's with a spacer.

I change from 30's to 40's on my Excella. The cover for the 30# tanks is about 4" to 5" to short now.

Thanks for the feedback, it is greatly appreciated.

Some follow-up on the project: I have purchased 2-40# Worthington tanks from my local Menards store. They are slightly taller than 29 1/4 inches, but still fit inside my propane cover which is about 29.5 inches high, (exterior dimension). That said, I also purchased a new 36" piece of 1/2" - 13 all thread to replace the current rod, as well as a few extra 1/2" nuts for anchoring everything down. Needing only about 30" of the all thread rod, the extra 6" will either be removed or "stored" below the anchor nut of the tank holder plate. I will lock this in place with 1/2" nuts on both sides to prevent it from cranking out on its own.

Anyway, the project is nearly complete and I'm excited to replace the twin 20# tanks the previous owner left behind(that's another story for another time).

Thanks again,

Pictures when you are done. I'm curious.

Previous owner of our trailer got a deal on a pair of 40#ers. All he did was add a longer threaded rod and the cover looks a little short. No problem at my end. Works great

Would you be able to post pictures of the 30lb cover with 40lb tanks?

How much extra weight did it add? I've considered aluminum tanks but they are pricey

Sorry I can't post any PIX. Our trailer is visiting a friend in North Carolina at the moment and I won't be picking it up until mid-December. Throw an eyeball on your current tanks and cover and just picture the bottom of the cover raised about 4" to expose the very bottom of the tanks. That's what ours looks like and for the cost of a new cover I can live with it. Mine are aluminum 40's and replaced aluminum 30's. I have no idea of the weight difference however I suspect it's not a whole lot more than the gas volume weight difference.
