Chile/Argentina by campervan and possibly South Seas

Seeking female travel companion for a campervan trip through Chile and/or Argentina. Preferably during their summer, which is our winter. See and experience + hike a lot: National Parks, cities, Atacama, Andes, mountains, glaciers, Patagonia, get to know the country & people. Campervans e.g. from Ruka or AndesCamper cost around €200/day, I can cover up to approx. €150 of that. I am a non-smoker/-snorer/-grabber. Similar plan for the South Seas, but without a campervan, maybe with a rental car?: possibly October-November due to storms + rain, starting December island hopping, visiting several islands: Fiji, Tonga, Cook Islands,..? Relaxing, beach, snorkeling, diving?, nature, country & people. Interesting offers from Miller, Gebeco, Diamar, Pacific Travel House, but very expensive -> possibly organize it myself? Flights approx. €2000 to €2500, initial costs quite high with €3-5000 from... :( Possibly also destinations in Asia + EU. Sympathy + humor important ... :)
