I think most of you are misunderstanding the question.
I am familiar with many of the travel rules, where I can and cannot conceal normally. I refuse to even get close to California, and the east coast is out my my travel range at least for now. My question is what changes does the motorhome make.
IE, I recently made a 9 western state car trip. I had to remember to unload and store the gun when I entered Colorado and tuck the shirt on so I was open carrying in Oregon because my permits are not honored there. However if the gun was back in the house portion of the motorhome would I still be required to unload? After all, it's in my home and even those two states would allow me to carry in my own home.

Well, there are federal and state laws. I guess that is not the answer you are looking for.
Inform yourself about the laws of EVERY state that you will be visiting. Some states, such as NY, have prohibitive possession laws due to possession permit requirements. Some states, such as MA and CA, have restrictions, such as magazine capacity and "assault weapons". States have different laws regarding what is considered an unloaded vs. a loaded firearm. States have different laws regarding keeping a loaded firearm in a motorhome. States have different laws regarding the castle doctrine in general and in a vehicle in specific.
