power for camper

Sounds good to me.. Hope so as I have just done what you have described. I have two deep cycle Trojans (105amp) in the Camper Trailer that get charged as we drive along and then if I stay in one place for a while I give them a squirt from my Christie" Gen" set. This only takes me an hour to fully recharge them from about 60%. Like you, all I run is lights and a Evakool 60l fridge freezer.Hope it is a success for you to.

what is a christei gen set

thank you for your help sounds like that will be the way to go for me because of limited space

if you can afford $1300 get a honda inverta. You will never have a problem they run on unleaded 2 litrs for 6 hours and has a 12 volt battery charger adapter. then you can run 240 fluro lights and all your fridges (a spa porch lights and a stereo).The car should charge you trailer when not stationary.
And they are quite!!

David,
I have a similar system and it works fantastic for me, I have been using it for a few years now, my only addition is a 80 watt solar pannel to charge only the dual battery system, I have a 700 cca start battery, two 80 amp/hr Delcor calcium Deep Cycle batteries wired in parallel and managed by a Piranha DB150E electronic isolator.
I live on beach's for many weeks at a time, and don't have to start the van to charge the system, as the usual drive to get food or water each week must do the trick for me. My Fridge/Freezer is a 50 ltr Liemack, (yes I can see some now saying stupid things about power consumption, hey it works for me so I don't worry) the fridge actually recharges the AAA and AA Batteries, phone battery and the camper lights, I have the radio and all other electrical accessories connected direct to the dual batteries.
Preperation is the key, do a few small trips away to figure out what you don't need.

Enjoy your trip....
