Kevin - It sort of depends on what you think you will be doing camping wise. If you are going to be camping off the power grid any you will probably want to have a few of the 120VAC and 12VDC items along with you and will need the batteries upgraded to increase the AH capacity to handle this load for a one day/one night camping run off your batteries. Most folks like to have around 220AHs battery capacity on board.
To make this work successfully you will need to have a good smart-mode converter/charger unit and a 2KW Honda type generator. The idea here is to re-charge your batteries every morning by running your generator for just three hours which will recharge your battery bank back up to 90% charge state and then you can do this all over again for the next day/night camping run.
Your older CARSON is out of business like said above and is a simple single stage charger which produces 13.6VDC voltage. This will not re-charge your battery in a very short time of three hours. It will be more like 12 hours to get the batteries back to 90% charge state.
I would replace this unit for a PD9245 or similar smart mode technology converter/charger unit that also has a regular Power Management Panel which has slots for multiple 120VAC circuit breakers and 12VDC fuse positions. This brings you up to the modern world haha...
We camp all the time off the power grid in our OFF-ROAD POPUP and run all of the 120VAC and 12VDC toys except air conditioner or high wattage microwave. This includes the HDTV, DVD player, all of the internal and external lights, electric blanket, NOAH WX alert radio, mood lamps, etc... When we go to bed and power down for sleep the trailer will continue powering up all of the sensors, maybe a night light, etc until the next morning. Then during breakfast we will connect the 30AMP shore power cable directly to the 2K Honda Generator and run the generator for three hours when allowed to do so by the camp ground and now we are good to do all of this all over again for the next day/night camping run from the batteries.
The squirrles like to watch alittle NCIS-CSI in full HDTV mode too...
Our camping setup looks like this back in the woods somewhere camping off the power grid... This is us at Wichita Mountains WildLife Refuge in Medicine Park, OKLA... Lovely camping spot amoung the wildlife including Buffalo, Cougars, and lots of Deer and Raccons hehe... You have to watch where you step after dark - might be mushy...
If we need a fan running around the picnic table to keep the mosquitoes off of us we just run a drop cord from the trailer and plug it in...
You can be successful doing this as well with just alittle planning and some modern mods to the internal lights, converter charger, and more batteries.
