Mount of Caulk Needed to Seal BTLE?

[jibsymalone]

As the title thread suggests, i am about to order some high temp silicone as i plan on getting my smoker this weekend and want to use it ASAP (of course!) I think i am going to take the plunge and get the brinkman trailmaster Limited edition. I  am planning on sealing the rig as i put it together. i was just wondering how much caulk most people have been needing to achieve this? Is there a particular caulk that is best suited for this application, i am planning on using Rutland 600*f RTV Black, is this acceptable?

Thanks to you all as always! hopefully i will have some Q views for you this weekend!
