If your going to buy new they will build you about anything you want I think. I would get it customized just like I want it. Take some quotes from a couple of dealers on a custom rig delivered.

One thing you may want to consider....if you fish a lot of big water in rough weather....you may just want to get a used bass boat. The aluminum boats are better than ever,but the reverse chine design of bass boats generally results in a dryer ride.The fiberglass in general rides smoother,and a good used 18 or 19 ft Ranger,Skeeter or other good well cared for bass boat will usually be well equipped with a ton of accessories,have excellent trailers and livewells,etc. You can tie up 15 to 20 thousand in a custom aluminum, and if you shop may find a good used bass boat for about the same money. If your in a Ranger R83 and you get caught on the water in a big storm it is a comforting feeling to know whatever happens it will float upright and level. You can also stay until dark 5 miles from the ramp,and when you get ready to get home your wife can tuck in behind that console and you can put that thing up on the pad and glide on in minutes.

Just a thought

It's just a thought for consideration.
