Camping with a Baby. Recommendations please!

Andrea • Tommy arrived 12-5-16 ❤️
I am going camping or "glamping" since we are taking a motorhome, at the end of June and I am looking for recommendations on what I will need for baby. 
My baby will be 6.5 months old. There are no electric or water hookups where we are going so I will be bringing an extra generator to make sure we have a cool place for the baby. We will be going to a lake with my family. 
I am asking now so I have time to order any items I will need. We take this trip every year so I will be using any supplies I buy for future children too so I'm willing to invest a little cash to make this comfortable. 
I'm not sure if the pack n play I have will fit in the motorhome. Should I purchase a camping high chair? Extra pop up for shade? Thanks for the help!
