A road trip across three h-u-u-u-g-e states in America - California, Nevada and Arizona, then back again - was a major learning curve for a mate and me in July. Though we'd both driven in the US before, we'd only covered short distances and were underprepared for some of the challenges a longer trip threw us. Here are a few tips.
• Use Google Maps rather than a GPS unit for getting around - if you have access to Wi-Fi you can download areas that your device can cache, which will work offline. Google will warn of accidents, congestion, etc, and plot another route for you, if possible. It will also help you to find gas stations.
• If you're in the US for a few weeks, check with local providers for prepaid SIM cards for tourists. You'll find this much cheaper than roaming.
• Campgrounds often have better set ups than hotels or motels, with laundries, free Wi-Fi, pools, games rooms, libraries and barbecues - but bear in mind you might need heating or air-conditioning at night, and some don't have kitchen facilities.
