California help with non commercial class A

Hi All...

I hope I can gain some insight as to what or who might be the best resource to help me.

My wife and I are contemplating traveling full time in the next 4 yrs. In the meantime we would like to buy a trailer or motorhome.

My issue is this... I see that a non commercial A will allow me to drive both a 45 foot fifth or toy hauler as well as a class A 45' motorhome. From what I can tell the non commercial class b only allows me to drive the motorhome but not the fifth wheel. I would like to get the A to give me the most options.

I have a couple of issues too... First is the health cert.. for a class a it is a dl546 according to the dmv website, and for a class B it is the dl546A.. The a form is filled out by a dr. where the 546 is a self filled out doc? Any ideas why that is?
The questions about the are because I am 45 almost 46.. but I have had high BP since being a kid, about 1.5 yrs ago I had open heart surgery to fix several birth defects, including a new valve. At this point my bp is good.. but I am on BP meds.. Should I be worried about the medical?

Since I don't own either a trailer or a motorhome yet, how do I test in one? Can I just rent one? The other thing about getting the license is you have to drive it to the dmv and or to practice with someone that has a non comm class A.. I don't know anyone who has that.. So ?

How do I legally get a license and follow the rules for CA?



Any suggestions?
