Welcome to the forum and congrats on your Tiffin Allegro purchase. We are 60' long as well and find most private parks have sites although some older parks may have very limited availability. Many of the newer parks are nearly all setup for big rigs, biggest issue is the older state & federal parks since many were built when a scant few big rigs were on the road. We flat tow and our setup was about half of what your dealer quoted, I do rigorously shop around for the best deals though. Here's hoping your Tiffin/Bronco combo delivers on all your expectations and that you enjoy RVing as much as we do.
