Most rigs are equipped with a gas stove and microwave.  Some will have a gas oven and a micro/convection combo.  They all work very well and are just fine for basic cooking.  Many of us use our crockpots and outdoor grills to supplement.

You will want to equip your kitchen with all your favorite utensils, pans, etc.  There will be room for all your basic needs and then some. While we are actually moving on the road, the use of rest stops, truck stops, etc. become the meal destination.  Just pull off, fix your meal, eat and go.

In motorhomes, you can actually fix a sandwich, get drinks, pop popcorn and keep rolling the whole time.  Of course, you can always stop at a restaurant that has parking spaces available for your rig.
