Chile/Argentina by Motorhome and possibly South Seas

Looking for a female travel buddy for a motorhome trip through Chile and/or Argentina. Preferably during their summer, which is our winter. To see and experience a lot + hiking: National Parks, cities, Atacama, Andes, mountains, glaciers, Patagonia, getting to know the country & people. Campers 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 in the South Seas but without a camper, sometimes with a rental car?: possibly October-November due to storms + rain, from December onwards island hopping, visiting several islands: Fiji, Tonga, Cook, ..? relaxing, beach, snorkeling, diving?, nature, country & people. Interesting offers from Miller, Gebeco, Diamar, Pacific travel House, but very expensive -> organize it ourselves maybe? Flights approx. €2000 to €2500, *starting costs* quite high with €3-5000 from ... :( Possibly also destinations in Asia + EU. Compatibility + humor are important ... :)
