Just as a heads up: Check out Costco as well. We got our batteries there for our new solar system saving a small fortune and the quote we got for tires apples to apples comparison for 6 for our MH ended up being $600 cheaper and half price for the labour/valves/balancing etc.
Happy Travels, we were virgin RVers back in 1999 and I remember it like yesterday how excited but nervous were we - past few years we've been doing more and more extended trips of 6 to 8 weeks, leave for one in less than 2 weeks, and within year and half will be FTer's. Be warned it can become addictive!
