30lb LP Tanks on an Expandable

Might be an easily answered question, but can you replace the 20lb LP tanks on an expandable with 30lb tanks?

We're picking up our ikss tomorrow and plan on switching the tanks. We did not measure clearance from the fold down bunk end.

Don't see why not. You may need a longer threaded rod for the attachment of the bottles and the hose going from the regulator to the TT chassis may be too short. You will probably need a taller tank cover. Other than that, I don't go through 60# in a whole season. How long does 40# last you?

The only thing I can think of other then what Jeff64 said is the added weight to the tongue of the trailer.

We are going from a fully enclosed surveyor tt to an expandable. The surveyor was our first tt. It came with 30lb tanks, so we don't know what it's like with 20lb tanks.

I usually take the 30lb tanks in and top them off mid summer. We do a lot of April/May and Sept/Oct camping when it's cool (still do a lot in the summer, but early and late are our favorite times), so we do use a decent amount of propane, but I've never kept track of it.

We try not to use LP for water heat and we don't often use stove top and never use the oven.

Dealer said they could switch them out, no problem. Also told us the underbelly on the ikss was fully enclosed and heated though before I got down and took a look! LOL!

Bottom line, I figured I'd ask the community to make sure before I start making arrangements for something that may not work. I'll ask them about the gas line length, I did not think of that - so thanks for the tip.

On both of our prior hybrids 30lb bottles would not fit. A 30lb bottle is almost 24" high and the bunk door would hit them when lowered. Those were both non FR hybrids and the bunk doors were hinged higher from the floor than a Roo or Shamrock. The 23IKSS and 21DK have the front A frame dropped below the main frame rail to accommodate the through the frame slides, so you would have a few more inches (probably 4) of room on those models.

There is not enough room to place 30lb tanks in the stock location and still allow for the front bunk to open. On my Roo 19 there would have been no issues with hose length, or the length of the threaded rod for the hold down though.

I moved my batteries inside, for various reasons, and this allowed me to move my LP tanks back and place a tool box where the tanks used to be. By doing so it lowered them also. When I measured there is now just enough extra height to use 30 lb. tanks The neat thing is that the original cover for the 20 pounders sits on top of the frame still so the extra height is underneath the cover so you don't need to change it either

We just got our Roo last September and I still have the 20lb. tanks on it but I could change them out now for a long trip. The other thing that I have thought of is on a long trip you might want to take one 30lb tank and your oldest, crudiest 20lb. tank. That way you don't have to search for a fill station on the road but can just exchange the 20 pounder wherever is convenient.

Mr. Havercamp has a point. If you have a 23IKSS or 21DK you might have enough clearance, since the tongue is lower than the main frame on those models.

Here are a couple of pictures of my setup. Note that the wood was a temporary solution to try things out and get things mounted quickly before a trip last fall. I plan to replace it with a simple metal support. Metal doesn't rot as fast as wood!

We are ready for our 3rd season with our ikss and we still have the original 20 lb bottles with the original propane. Apparently we don't use much. We camp mainly in state parks with electric hookups, no water at site. So we run a small electric heater for spring and fall and seldom use the furnace. I've probably used more propane in the bumper mounted grill than in the furnace.

30# tanks

When we went from our hybrid to a TT ,the TT came with 30# tanks and we switched them out for 20s. We camp in Ontario from May to October for a total of about 6 weeks and in 5 years of trailer camping (some of it dry) we have never even had to add to the tanks in the summer. We mainly use the propane for heat & sometimes to heat water. We just felt the smaller tanks added less weight & were easier to refill when needed. Stick with the 20#.

30lb LP Tanks on an Expandable

All great advice. Thanks for the help. There's a lot to be said about the ease of exchanging 20lb tanks vs 30lbers. There's always a lot of 20's ready for exchange at campgrounds. We'll probably stick with the 20's.
