Hey all. I recently inherited an older Viking SP190 pop up. It needs some work and doesn't have really many features at all. No HVAC/heat, no fridge, no stove, no sink. Has a couple of lights and a few outlets. What I want to do is either replace my lights with LED bulbs or buy separate LED strips to be mounted inside for lighting, add a 12V plug or 2 to charge cell phones, be able to run a fan to keep air moving in the camper while sleeping, and power my CPAP once I get the 12V adaptor for it. Very minimalist by my standards. I'm hoping to be able to set this whole thing up to run off a battery or 2 with solar recharge capabilities. I do not intend to run any 120v accessories through this setup. Only what's in the paragraph above. Realistically, what should I be looking at to make this happen? Do I really need a high dollar setup to make this happen? Thanks in advance.
