Insulated Fire Box?

[Pa_BBQ]

I am considering upgrading from a TS120 to a TS250 and the insulated firebox is $795.00 and wondering if its worth the money.

Will an insulated firebox give me a longer burn time, or just hold temps better in cold weather.

What other advantages are there to a insulated firebox.

Looking to sell the 120? (not that I could buy it just yet )

May sell it, trade it in, or just cut it down and make it a patio model that can git on my trailer.
