After more than 25 years of full time RV living, mostly in remote areas, I make the following observations.

The most dangerous threats are fire, flood and trees.

Fire: If you are in a remote area, a lightning caused fire will prompt heavy traffic into the affected area. You may be required to leave the area with less than 10 minutes warning. The road will be restricted to fire traffic only so you will have to abandon your rig and ride out with only hand held baggage. They do not want to risk a camper blocking the access road. We (wife & I) keep pelican cases with important items like medicines, papers, laptop radios etc. Under crowded conditions, you may be required to stack your gear in the back of a dump truck which then travels miles over washboard roads while you get stuffed into a van or other conveyance. Only a small personal items bag can be carried. The advantage of the pelican case is that during normal times, it can sit open on our seat next to us, allowing easy access and ready for quick inspection to make sure all needed items are present. When we have to leave, a quick scan assures us we have all the important stuff. The small handbag contains meds, radio, cellphone and other must have items.

Situational awareness is the most important task while in the back country. We carry radios which are capable of monitoring the controlling agency major radio traffic. Most is not encrypted and signals are usually very strong so no expensive equipment is needed. Usually there is a daily situation report that will warn you of unusual dryness or other "red flag" conditions as well as road closures etc.

Flood: Never camp at the lowest spot. A major rain storm miles away can cause very rapid flooding, from dry to raging stream in 2 minutes or less. So keep track of weather not only where you are, but in the surrounding areas as well. Inspect the roads as you travel. Look for low spots that may be flooded blocking your exit.

Trees: We have pulled into prospective camping spots to find a large limb laying right on the best camping location. Sometimes it is hard to see a dead limb above you. I usually walk away and scan the trees over our prospective spot with binoculars. Look for limbs with no leaves or broken branches which may mean parts of the tree are rotten.

Take simple precautions and you will be ready for most things. Our camper is a Dodge 1 ton 4x4 with a slide in camper. In our 25+ years we have managed to avoid loss or injury while enjoying life in the most remote areas in the USA, Canada, Mexico and South America. Situational awareness has allowed us to be preemptive with our actions, staying clear of potential threats and reducing the stress of the unknown.
