Having owned three different RV GPS brands, I have to say the Garmin is the best. And with all GPS systems no matter what brand, you still have to pay attention and look out the window. Unless tom tom has settings for an RV, I would avoid that brand ...
I have had four units with ovens, which were used for storage. Our current unit has a Convection Oven/Microwave and no oven. Works great. Previously, we used an electric potable convection oven when we needed it.
