Steve, either charger will do a good job. The 25 Amp one will just do it faster.
I bought a 7 Amp CTek about 5 years ago when I only had one battery to charge and normally had access to 240 V. We now have a lot more batteries (360 AH in van, 210 AH in vehicle and 100 AH in boat) and regularly use a generator (despite having 490 Watts of solar). I now have a 25 Amp CTek which we use as a portable charger and a 40 Amp Centaur hard wired in the van.
After a few experiences over the years with not buying
well first time, I now always recommend getting the 'biggest' and best of everything first time (budget notwithstanding).
A 25 Amp charger will give you more flexibility (faster, more capacity if you add another battery or another fridge, etc).
I would go the 25 Amp, but as I said above, the 15 Amp will do the job you want, just a bit slower and with less flexibility for the future. But it is your money, budget and set up. I can only advise based on my experience.
