92 serena question
 

hi there, i recently bought a 1992 nissan serena, took out the seats and am living in it while i travel around new zealand. (im Irish) the question i have is this: i bought a second battery, to be charged by two solar panels im gonna place onb the roof. i cant think where to put the second battery though. ive thought about getting a spacesaver spare wheel and perhaps fabricating a shelf for it where the bulky spare wheel would normally sit... i really dont want to put it in the cabin, because of fire risk, gasses etc.

if anyonbe has any ideas or advice im all ears. also, its an automatic, i was wondering what the common things that go wrong with this model are. theres 220,000 k's on the clock, and the bodys in excellent condition.

many thanks,
ned .
