..Here's one more vote for 'Just go to Florida, get your new Motorhome back home, enjoy the excitement of it, and worry about the license part later'.
This is a subject I've researched quite a bit, as has my BIL (brother in law) who owns a large 5th wheel. We have discussed this with highway patrol officers, DMV officials, and RV dealer reps. Bottom line is, like already said: It is very, very unlikely, even if you do get stopped for something else, that any law enforcement officer will ever notice this, let alone cite you for such. Most law officers as well as DMV officials will not know about and/or will not care about just what specific RV type would require a B license and what would not.
Only risk would be in the event of a major accident, where everything about you and your rig would be scrutinized. Yes, in that case, not having the B license could be a problem. Thats why you should probably get the license, eventually, but I don't think you need to just for the 1 trip home with it.
Even RV dealer reps in North Carolina that I've talked to, that drive these rigs as part of their job all the time (to RV shows, etc), in most cases do not have a B license! They do NOT require you to have such license when selling you one, either. They do remind their customers that technically they are supposed to have such license, but thats it.
Go get your Motorhome, and enjoy it. :)
On a sidenote, thats not very helpful but I'll say it anyway: This issue with NC drivers licensing, is yet another of the many reasons we chose and will stick with our gasser MH and its GCWR under 26,001 lbs: I don't have to worry about getting any special licensing to drive it, as DP owners do in many cases.
