Go to RV Driver Confidence Course - Lazydays RV - Number One In RVs (Gas & Diesel Motor homes, Fifth Wheels, and Travel Trailers)
and consider this course.
In addition, some things I have picked up over the years.
1. Adjust both right and left mirrors so you can just see the side of the coach (the upper mirrors). As you drive down the road, you can use these mirrors to see the lane markers. If you can see both sides lane markers, the coach is correctly positioned in the lane.
2. Adjust the lower side mirrors down and outward so they can clearly see the lane next to the coach. My lower (convex) mirrors are adjusted to they clearly see the lane next to the coach all the way to the rear of the coach.
3. The mirrors should show you a vehicle approaching from a distance (upper mirror). As the vehicle approaches the rear of the coach it passes to the convex mirror until it can be seen by the driver.
4. I drive with my back-up camera on all the time.
5. Have a helper stand next to the rear axle next to the coach. Place a small dot on the lower mirror where the assistant's feet are. If you have a tight turn to make, you will know where your pivot point is by watching the dot. As the dot passes an obstruction, you can safely make the turn.
6. On the front windshield, I have two small lenses that allow me to look almost straight down to the bumper.
7. With a helper and a measuring tape, measure 15 feet Freon the front of the coach. Have the helper stand on the 15' marker. Sit in the driver's seat and place a small dot on the windshield where the helpers feet are. Have the helper move toward the coach until their feet disappear. The helper should note via the measuring tape how far they are from the front of the coach. Now you know why have the two small lenses on the windshield. On my coach, the helper's fee disappeared at 12' from the front of the coach. Without the lenses, I can not see what is on the ground up to 12' in front of the coach. This aid is for maneuvering in CGs.
8. The manufacturer of the coach's engine can tell you the RPM range that will deliver the best fuel mileage. For me, it is 62 MPH. That is what I cruise at.
9. Use the exhaust (engine?) brake when descending mountains. The service brakes should be used for routine stopping.
10. Diesel coaches do not accelerate, they gain momentum.
That is all, for now.
