iOverlander is a mapping app to help travelers find camping and accommodation worldwide - no matter how remote your destination. Only real places by real travelers. Unbiased and never sponsored. There is no list or robot that can ever replace what a traveler says standing right there in that spot. Typos and all, we believe the best data comes from overlanders onsite. No signal? No problem. The best places on this planet don’t have cell signal. All our data is stored on your phone, so you can plan your day without wifi. Download offline maps of entire states and countries, that give you all the tiny alleys, building footprints, and small landmarks to make travel easier. Campsites are just the beginning. Mechanics, restaurants, hotels, propane, water, wifi, shopping, laundry, showers, doctors, tourist attractions, border crossings, warnings, checkpoints, insurance, storage, shipping, consulates, banks, and more. Moderated by overlanders, not AI. Our moderators have spent a collective century on the road and 30,000 hours moderating entries. They’re not planning to stop anytime soon. But wait, there's more! In addition to finding places, you can add new ones, leave reviews, save favorites, and share places with other travelers.

About

ProMasterLevel

Features
Read full description

ProMasterLevel is a leveling app for Dodge RAM ProMaster-based campervans. This app handles three Promaster wheelbases, and it can also be customized for any RV. This app shows how much lower three tires on your van are than the highest tire, the reference tire. These values can be used for re-parking or for choosing leveling block heights. Leveling biases can also be entered into the app, so you can make the sink drain work better or ensure your head is higher than your feet when sleeping. Sounds can be used to level your van with this app. You can set a level tolerance value and chose a sound pair. One sound will be played if you are out of the level tolerance range. Another sound will play if you are within the tolerance level. For example: You can choose a level tolerance of 2 inches. Then make sure the audible icon on the upper left of the main display is activated and put your phone on a flat surface. Get in the driver's seat and start moving your vehicle. The app will tell you when you are out of and within the 2 inch level tolerance limit. The FordTransitLevel app also has a 'Gear Left Outside' GPS alarming feature. If you put stuff, or plan to put stuff, outside your van ... you can use arm this alarm as a reminder in case you drive away and leave your leveling blocks, or generator, or mountain bike, etc. Once the alarm is armed, the app will run in the background. When the app sees that you have traveled past a selected alarm distance, it will send a notification to the phone. Three distances are available for the GPS alarming "geo-fence". These distances allow you to arm the alarm and then walk around your campsite without setting the alarm off. The FordTransitLevel app will quickly pay for itself it it means you don't drive away from your $1000 generator or a $2500 mountain bike! SprinterLevel is a standalone app. No connection to the Internet is needed. Similar iOS apps, by the same developer, are the popular SprinteLevel and RevelLevel apps.
