so opted to get the RV specific GPS......I don't want to have to depend on cell service so still want stand alone GPS.

I have decided to go the same route as you with the Garmin 770.

As for 'stand alone', I think pretty much all Ipads and tablets ARE stand alone. They work off of the satellites and not wi-fi for GPS operations. I use my Tablet on my boat when long range cruising as a back-up GPS. The real down side of Tablets is that GPS really uses up the batteries. When traveling, I have the Tablet on GPS mode and plugged into a 12V accessory socket. It eats up the battery faster than I can keep it charged. it will go to almast zero charge in about 7 hours - with the accessory 12V plugged in. I also noticed that when I downloaded the marine program it stated that in GPS mode, it will shorten battery life - they are not lying.
I'm pretty sure I will go with the garmin and a Tablet App for back-up.
Anyway, thanks all for the input.
