I am looking to do trip down the South America in 2015 from Alaska I have done trips on my bicycle an motorcycle for 2-4 weeks at a time but am looking to build my 2013 JKU up for this adventure..., any mods you guys would suggest... I already have snorkel,2.5 lift,35s, plenty of lighting, tools... And what do you think this trip would cost round trip. I am also gonna be staying in a RTT. Thanks for any input
