Picking up a 12 Solera next week. This is my first RV and I'm clueless. Leaving on a cross country trip with my 6 year old son in early June. Any travel tips and advice would be greatly appreciated. I have been across the country in cars probably 30 times, have slept in my car or hotels in the past. I would probably be less worried if my son wasn't coming with me, but he is the reason I bought it in the 1st place. I have my orientation Monday. I have no idea what I need to buy. Thanks in advance for your consideration.
