Welcome Christine.
So sorry for your loss. This is a great group with lots of advice, compassion & laughter.
I can't offer much advice on your rig, but these gals are right - give yourself some time to figure it out.
I even questioned my van when I drove it home for the first time - pretty much white-knuckled most of the way.
and it's little compared to what you have! Now, however, I'm as comfortable with it as my minivan.
And its such a joy to be able to just take off & know that I have everything I need with me.
Hope you can meet up with some of these ladies - they're terrific!!
