I registered mine as a commercial truck for private use in NV.
This is only way to register them in NV, you'll pay normal registration fees, for that ended up being about $750.
I insured through Progressive the same way, this way I can drive it bobtail. If you insure it as an RV you find that your truck is only covered when pulling the camper, this doesn't work for me.
I had no issues registering it, was in and out of the DMV in about an hour and a half (they are not making appointments for private sales)
I plan to get my Class A Noncommercial, however they are not making appointments for non CDL drivers, so that will just have to wait. I have had no issues and have been driving it for several months now, even got a few thumbs up from NHP officers lol
