Hi Mike,
I've been happy with the Dual Pro. Are you looking at the reconditioned units http://www.dualpro.com/store/items/9/25/ ? Good prices. As I understand it the charger I got was installed on a "Skeeter" (bass boat?) for the trolling motor power charging. The boats were never splashed so they are basically new, I may be spreading an internet rummer here :-). Anyway the Dual Pro has worked great and did what I needed it to do - balance a new battery into an existing bank.
Regarding mounting; I have had good luck with construction adhesive (polyurethane adhesive) for gluing wood to fiberglass. I glued two 1x2 strips of pine to the hull near the second bank and screwed the charger to them. You could glass over the wood strips, I did not. The seas can get pretty active here in the Pacific and I have had no problems with the mounting.
I do like the redundancy of two chargers.
I added a photo of the Dual Pro mounted in my boat in the photo section here under Lotus Flower.

I'm doing this to hopefully keep the four 210 amp AGM batteries in the bank in a better balanced state when charging rather than just using the Zivan which sits across the entire bank. I'm also hoping I can use this second charger along with the Zivan to add a few more amps to the controller when motoring and hence more speed without depleting the battery bank. But, the primary purpose will be to balance the battery bank. I'm considering two quad chargers
