I just purchased a 2006 LX 470 stock no nav and no kdss. Everything is functioning correctly but Im uncertain about when/if the timing belt and water pump were serviced(current mileage 141000). Im looking to get into overlanding and I am curious about what aspects of the vehicle to upgrade first. I know I would like a 3 inch lift with 33 inch tires, full roof rack, steel bumper with winch, and armor. What would be the most sensible order to go about upgrading and also what other upgrades should I be considering? My budget will be about $300 a month over the next 3 years.
