What should be the licencing requirements to operate large motorhomes? My opinion.

Having obtained the required licencing to legally operate our motorhome,  I would like to reflect on those requirements.  Currently, the Ontario MOT requires that everyone driving motorhomes and towing a vehicle with a total weigh exceeding 11,000 Kgs (24,250lbs)  have a "D" commercial truck drivers licence.  I believe this to be unreasonable.  It also has a major impact on the RV industry who are already suffering from a slow economy and high fuel prices.
 D- licence requirements come with some major assumptions which are reflected in both the the D-Licnece training and in the ultimate testing by the DriveTest Centre.
With both Bettyann and I having gone through the training and having obtained the required D-licence to operate our motorhome,  we believe that it is unnecessary and definately overkill.   If every retired person, with the dream to purchase a motorhome and travel North America,  after 50 years of work, has to obtain a commercial truck drivers licence - that dream will be unnecessilarliy shattered.
The D-licence requirements is clearly focused on young healthy adults seeking employment driving a truck.  Both the training and testing reflect this.
Here is what I see as some of the assumptions - there are many more:
1.  The truck you will be driving will be owned by someone else and will not necessarily be well maintained.
2.  The driver has very little experience driving and only recently obtained a G-licence and may not be familiar all the road signs, rules and commercial truck requirements.
3.  There is a necessity to know about the mechanics of the brakes, engine components and truck sturctures.
4. etc etc etc
Let face facts,  motorhomers have made a substantial financial investment to own a motorhome.  They don't rent them and they maintain  them well.  Given it's size and cost the largest demographic are retired seniors with many years of driving experience.  I have not been able to find any statistics (I suspect that's because they don't exist) but I also suspect that the highway accident rates would be significantly less than any commercial vehicle.   Before they move, they know exactly how the vehicle will  perform.  The things you check, on a pre-trip are vastly different than those on a commercial truck.
The D-licence and the $1000, per driver, that you will spend to acquire it, is severe over-kill.  In order to obtain a D-licence you are required to:
1. Have a G-licence
2. Obtain an Air Brake Endorsement (Z-endorsement) which you have to renew through a written test every 5 years.
3. Pass an MOT required medical.
4. Obtain a driver abstract
5.  Pass the D-licence written test
6.  Pay for a training course to obtain information on the requirements to drive a commercial vehicle.   Yes, you need this to pass both the written and the driving test.
7.  Know nothing on what you actually need to operate your motorhome.
So, having gone through the process what do I believe you actually need to drive your motorhome?  A G-licence!  You've actually learned a lot by having driven various vehicles over 50 years.
By the time you finish your test drive, purchase your motorome and drive it off the dealer's lot you will have all the knowledge you need to operate your Air Brakes.  After all, the G-licence doesn't require you to understand your hydraulic brakes.  My motorhome is 40 feet long and 42,000lbs.  I know the minute I get in it, that I need to be careful how I turn it so I don't damage it taking out a stop sign cornering.  I know I have to leave extra space to accomadate stopping with the extra weight - you learn this really, really fast probably in the first 5 minutes of driving.
