Our maiden voyage in our coach was to an FMCA Rally and it was well worth it in several aspects.
+ There were several planned additional and upgrades I was able to have performed at the rally. I had our tow assembly installed on our coach/toad, had service work performed and had some accessories installed, all right at our parking spot in the rally campground. Talks about convenient. I arranged some of these before hand and at one point four different service teams were working on our coach. Some of the work was done the day before the rally actually started.
+ We spent much of our time in seminars and learned so, so much that we did a second rally a few months later just to catch some of the seminars we could not fit into our busy calendar.
+ Many of the vendors selling goods and services offered a rally discount and I made sure to ask for a discount if they didn't mention it.
+ I you are considering an accessory or upgrade and looking at two or more offerings, a rally is a great place to compare them directly and hands-on.
+ It is very important that you get the corner weights of your loaded RV (full fuel and water) as the actual weight is critical to properly adjust your tire pressures. A coach weighing service is available at most rallies but book a weight time early as they sometimes run out of time to do all the coaches.
Of the two rallies you mentioned I would suggest "Escapades". It is put on by the Escapees, one of the best groups out their to join, in my opinion. They also have a Boot Camp for new RVer taht would be worth considering.
Enjoy. We bought our coach a little over two years ago and we've only been back home for about 6 months since then
Retired and livin' the RV dream!
