40 gal. Propane tanks?

[Dave and Beta]

Wow! That could have been a disaster. Need to take a good look at that. Thanks.

I purchased a 3rd 30 pound tank I carry with us all the time. I use it for our Coleman Camp Stove as the on-board quick gas line disconnect on my Montana does not work with my Coleman camp stove.

Meanwhile, that extra 30 pound tank comes in real handy when winter camping, using it as a back up.

However!!!! The circumference of the tank is just slightly larger than my originals. (And I purchased this tank from my local RV dealership too!) That means, those metal straps that wrap round the tank in the propane tank cargo bays is too short and won't snap tight.

That's no problem if sitting stationary, but when traveling, those tanks need to be strapped down. So, when using the tank as a back up, when it comes time to travel and one of the originals is empty, I'll swap the empty one back and stow away the 3rd one.

So, before purchasing a new tank, check the circumference and make sure it's identicfal.

But, if you don't mind the weight and making some minor adjustments in your propane bay areas, a 40 pounder will work just fine.

I've considered swapping out mine for 2 - 40 pounders, but since I already have the extra 30 pounder, I finally ruled that out because using 2 - 40's is 80 pounds and carrying 3 - 30's is 90 pounds. So, actually, I'm ahead 10 more pounds!

I carry the extra tank in the front compartment (under the trailer king pin) through, upright, snugged all around with totes.

The 30 and 40 lb tanks are the same size. 40 is taller is all. I switched out my 30 tank for 40 tanks. Fits just fine. Dont need to move the staps.

I have a different tank than original and I can barely hook and tighten the strap. Very difficult. I even bought a different strap and same problem.

Our #40 tanks weigh ~70# when full.

I keep two spare #30 tanks in our basement. They fit perfectly in a heavyweight plastic milk create.

Check to see if your tanks have two small raised ridge lines around the circumference at about the 1/3 point. If the retaining strap crosses this raised ridge, it will be difficult to fasten. I repositioned ours just above that ridge.

Thanks c2icliff. I will look into that in 2 weeks when I get my rig out.

I switched to 40lb tanks, no problems. I had to move the regulator up a little on the right side; no problem just a couple screws. I welded in some extra support on the tank platform to handle the extra weight; not sure it was necessary, but easy to do.
