I am thinking of buying a 1875 Lund Crossover but I have a couple of questions hopefully someone here can answer...

I have a boat with an Ulterra and Helix units all networked that I am use to and want to keep.

A. The boat comes with a 24v Terranova and I want to move my 36v Ulterra to it... is there room to add the third battery easily?
B. It comes with an Lowrance HDS9 in the console, can I leave the HDS and add my Helix's to the bow and back with no interference between the two makers? Or just plan on removing the HDS?

Or pass on the boat and wait for one that is closer to what I want?

Advice please... talk me off the ledge!
