This is why God invented RV'ing! What do you mean he didn't invent it? ;)
You and your little one will have so many fond memories of these trips. My kids still reminisce about trips we took 20 years ago. It's so much fun to go back and look at those photos from yesteryear.
And don't worry - all kids have meltdowns. I have video I took of a trip to Lake George when my oldest daughter was only a year old. We were trying to get her to take a nap in the PU, so when I was describing the CG on the video, you can hear her screaming at the top of her lungs in the background because she refused to go to sleep.
