Check out the undercarriage.
Really! You will want the one with the best ground clearance! Getting into and out of gas stations without worry about rubbing is great, but also you need to make it deep down the gravel roads to the best fishing spots too!
A class A will probably have factory installed jacks. Most class C's do not due to their limited GVWR. Also if your plan is to collect rocks or something, the class A will have a higher cargo rating. Sometimes a class C will not be able to tow much more than 5,000 pounds, and usually not 'good' at that.
Most class C vans are built on the Ford 14,050 pound GVWR E-450 chassis. WHile most class A's are built with either a GMC or Ford gas engine and 18,000 - 22,000 GVWR, with a few using even higher 24,000 GVWR chassis. So you can see that class A has the great advantage.
There where class C based on the GMC Topkick truck chassis with a 8.1L gas or 6.6L diesel engine. IT had a 19,500 GVWR, and where made up until about 2007 or 2008? Sometimes called a "Super C" - that was the trademark name of one RV manufacture. So it can not be used by other manufactures.
International also built class C chassis with it's 6.4L diesel in it. I guess a LOT has been written about the 6.4L used in Ford trucks, and it is the same engine. Put a coolant water filter on it, and they are pretty reliable.
I would put a coolant filter on anything that is as expensive as a RV. I have one on my Bounder with 460" engine that I bought new in 97. I change the filter each fall, because after it plugs, the heater stops working. It is inline with the dash heater hose. Kit #FIL 4019 is the mount and 5/8" hose kit, and the FIL 4070 is the small filter. You can get larger ones, and ones with SCA's built in. Napa part numbers.
Good luck on your RV purchase!
From what I hear, if you take the Alaskan highway at 45 MPH in the gravel sections, you will not be blowing out the tires on potholes. It is those going 65 that hit a pot hole and have a blowout soon afterword.. . .
My buddy in Fairbanks bought his car in Florida, then drove it back to Seattle, where he had it shipped by sea to Anchorage. This way he would not tear it up on the alaskan highway. . .

Money can't buy happiness but somehow it's more comfortable to cry in a
Porsche or Country Coach!
If there's a WILL, I want to be in it!
I havn't been everywhere, but it's on my list.
