First thing I would do it make sure I was doing all of the driving, not the DH. He sounds like my ex, scariest driver ever. If you are behind the wheel, you will be in control of the rig, how fast you are driving and so on.

If it were me, I would just to out and sit in the drivers seat to get accustomed to the big windows, take all the time you need. Then if you can't go to an RV driving school, go to a big empty parking lot and practice a lot as mentioned earlier, learn to back up, stay in your lane, any other kind of driving your feel uncomfortable with. Take as much time as you need, if anyone tries to make you hurry up, tell them to take a hike. You need time to be comfortable with a new rig.

Moving up to a bigger rig is scary at first, especially from a C to an A with that huge window, but if you are in control/driving each trip will get much easier until you get to the point you will wonder why you were scared to drive.

If you don't want to drive, always sit in the passenger seat, belted in, that way you can anticipate problems early and prepare for them. I'll bet that the unexpected manuver is what scared you more than anything.

Take care, you will enjoy the RV alot in time.
