I have a 2017 Lund 1875 Crossover and I believe you can make it work. The front of my boat has a storage compartment on each side with the 2 batteries installed ( 1 on each side). You could take up some of the storage and install the extra battery. As far as the units goes I have a 12 inch Helix Ram mounted to the right of the console. It is a tight fit with windshield but it fits. You could do the same and leave the HDS for mapping.
