Advice needed on smoker build

Guys looking for a little info, I have a friend who works in a machine / welding shop who is willing to build a Fat 50 style cooker for me, The thing is he wants to use 304 stainless steel for the build, is this a good quality metal for a smoker like this? I guess i am asking what are the pro's/ and cons of doing an all stainless build?

Thanks for the input, i thought that stainless would hold heat better, Would it really make much of a difference as far as heat loss? Price is not an issue, the place he works charges $.20 a lb for the scrap pieces, he has already built a wood stove and parts for my UDS for me. I kind of like the streaks of color that stainless changes when it is heated. I will see what other types of metal he can get.
