1.2 amps is not really at lot of amps for keeping your battery charged to it's fullest. it might work if the battery is 100% charge but it will not bring it back to 100% once it starts to lose it's charge.
Found a Coleman solar at Canadian Tire for $29.95. I was told that they go on sale for $10. Just saw one installed on a new coach - bolted to the grill in front of the engine connected direct to his battery. - he also had one on the dash which was plugged into the 12 volt outlet and charged his house batteries while coach is stored for winter. Thanks for the comments fellow RVers!
Looks like COLEMAN also sells a 6W model SOLAR battery charger
