Recreation.gov is a great place to check out federal campgrounds -- BLM, Corps of Engineers, National Park Services, etc. With an "America lhe Beautiful" card you can stay for 1/2 price. An RV buddy uses the qualifier that everything that goes in her antique 26 foot GMC must service 3 purposes or it stays home. She is the only person I know that has empty storage space in her RV, yet has everything she needs and her husband has room for his tools and spare parts (The GMC's do not have basement storage -- everything is stored inside the coach).
Congrats on the new PC and safe travels.
