Davy Crockett GMG - Generator question

[airforcemike]

Looking to purchase one as I have a Daniel Boone and love it but now want one for travel. 

Any suggestions on a decent generator that's not too big to run it!

Davy Crockett is 12 volt DC, just use a Deep Cycle battery or your RV battery...

Use the supplied 120 volt ac adapter when power available..
