When I purchased my 2026 Paradigm 340 rl, I asked dealer to install 40 lb propane tanks in place of the 30 lbs ones. They did this, but they used ratchet straps in place of the metal ones that came with it. They said they could not get metal ones big enough. I think that's BS, and not even sure that's legal. They work themselves loose and I need to keep an eye on it and keep tightening it. I was wondering if anyone in the forum had similar problem or recommendations. It was not a factory option with Alliance but they sell the suggestion that there is enough room for upgrading the tanks to 40, so I did.
