I'm over on the Island and just got a new NL 10.2. I too was thinking of deletions. AC, microwave, stereo, TV. But as my wife pointed out, deleting them might affect resale potential. And the $ savings and weight savings were likely not a massive savings anyway. And as others have said, you don't have to use them, but if needed, nice to have it there.
We went with a F350 dually, due to it being a 10.2. As others have said, take a bunch of trips with the TC and truck stock. No sense spending $$$ on stuff you don't need. Get a feel for what it's doing. If there's something of concern, then post what you are unhappy about and hopefully get some advice from those on here, with similar rigs and same issues. Not a guarantee of a solution for you specifically, but at least a rough idea.
It's not going to drive like when empty so keep that in mind. I think multiple trips are the best idea as it gets you experience with your rig and gives your brain and butt time to make adjustments to how you drive with the TC on. It's gonna do things that feel odd, even scary to some, but it's a matter of if those things are outside "normal" or not.
Save your money for now and enjoy!
Congrats!
