Driving an RV the first time

Lessons

1. 1

   Mirrors and the blind spot

   10 min

   An RV's blind spot is dramatically larger than a passenger car's. A Class C has a blind spot extending 10 to 15 feet down the right side that a normally-adjusted mirror does not cover. The fix is to adjust the right convex (round) mirror so the right rear wheel is visible at the bottom edge, and the right body line is visible at the inside edge. The flat mirror should show the lane behind you with about an inch of body line visible at the inside edge.

   On a Class A, the left side mirror is your primary lane-change tool because the right blind spot is wider still. Some Class A operators install a passenger-side camera; if your rental has one, use it.

   Practical rule: never change lanes without checking the convex mirror, then the flat mirror, then the convex mirror again. The convex first shows you the lane right next to the rig; the flat shows you traffic farther back; the second convex check catches anyone who moved into the gap.

   The parking-lot drill

   12 min

   Before you leave the host's property, do this drill. Find an empty parking lot or a quiet residential corner. Drive forward 50 feet, stop, and check both mirrors. Drive forward and execute a right-hand turn around two parking-space lines (a roughly 8-foot radius). The rig will swing wider than you expect; mark in your head how much extra space you need.

   Now back the rig up. Pick a target — a parking cone, a tree — about 30 feet behind you. Use the mirrors only, not a rear-view (most RVs don't have one). Back up slowly. The rig will drift; correct with small steering inputs. If you cannot back the rig 30 feet in a straight line, you cannot back it into a campsite. Do the drill until you can.

   Now do a parallel park into a single street-parking space. This is the test. If you can park a Class C in a parallel space without curbing a wheel, you can park it anywhere. The host's property is the safe place to fail.

   Lesson checklist

   • Drive forward 50 feet, stop, mirror-check.
   • Execute a tight right turn — note the wider swing.
   • Back 30 feet in a straight line using only mirrors.
   • Parallel-park into a single street space.

   Mountain passes

   12 min

   An RV climbing a 6% grade at 10,000 feet loses roughly 25% of its rated power. A 7,000-pound Class B climbing Independence Pass will run 30 to 40 mph in second gear; this is normal turbo behavior and not a failure. Stay in second gear, do not floor the accelerator (which generates heat without speed), and let the truckers pass.

   Coming down the other side is the harder problem. Brake fade is the failure mode: continuous foot-on-brake use on a long descent overheats the brake fluid, which boils, which causes the brake pedal to go soft. The fix is to use engine braking — shift to a low gear and let the engine hold back the rig — and use the foot brake in pulses, not continuously. Modern automatics have a low gear accessible through the shifter; use it.

   The runaway-truck ramp signs you see on western highways are there because trucks have lost their brakes on these grades. RVs can too. Drive the descent at 35 mph in second gear; the truck you are following at 25 mph is following the rule.

   Wind and the three mistakes

   11 min

   Crosswind is the underrated risk. A Class C is a tall box with a flat side; a 35 mph crosswind generates 600+ pounds of lateral force, which feels like the rig wanting to drift across the lane. The fix: slow down. Crosswind risk drops geometrically with speed. 65 mph in a 35 mph crosswind is a different vehicle than 55 mph.

   Three first-time mistakes that account for most reported incidents. First: turning right and clipping a curb or signpost with the rear of the rig. Solution: take the turn wider than instinct says, and use the right convex mirror through the turn. Second: hitting an overhead obstacle at a gas station or drive-thru. Solution: never drive into any covered structure under 12 feet without measuring. Third: forgetting to retract the awning before driving away. Solution: a pre-departure walkaround checklist that includes the awning latch.

   Lesson checklist

   • Pre-departure walkaround every single departure.
   • Right turns: wider than instinct + convex mirror.
   • No covered structures under 12'.
   • Crosswinds: drop 10 mph from cruise.
