After using the traditional leveling blocks on our Class A Motorhome for five years we were anxious to find something better for our Avion.
Kevin is a YouTube Research fanatic and thank goodness he is! He found the Anderson Levelers System which is THE best thing going.
They are a bit more expensive than the blocks but are sturdy, rugged and do a far better and quicker job. They store easily too!
We purchased the deluxe kit which also included an extra leveler and extra chocks, etc. The Rapid Jack leveler also has come in handy with some challenging elevations we have encountered. It is called their Rapid Jack and it works on duel axles to allow for tire changing.
Here is a great video to show you how they work.
The only thing we did wish that the levelers were just another two inches wider because we would prefer our tires did not extend past the levelers at all. This issue does not affect their use though. They are awesome! Also as some users have recommended, on certain terrain they could slip when you are trying to roll up onto them. We did find what happened to us at one campground was the campsite had a lot of fresh new small gravel and our leveler plowed forward rather than the tire being able bite and roll onto it. We believe fixing some of those stair tread asphalt type strips would solve this problem.
Get some! You will not be sorry!!
