We are recently retired and just purchased a 22 ft. MH, we live in Florida. My question is: we want to take a trip to Yellowstone, Grand Canyon, Mt. Rushmore, etc this fall. We are thinking of going around Labor Day to avoid all the crowds. Is there a good rule of thumb as far as time to go? Will the parks and facilities still be open after Labor Day? Will the weather be a problem as far as driving? Also, would 400 miles per day be too much to expect to get there? Any suggestions as to the route to take and any areas to view coming and going would be appreciated. We are not into shopping, like the more scenic routes and try to avoid the heavy traffic and crowds. Once we get to parks are there better places to stay over others for us first timers? Are we trying to cover too much in our first trip? Thanks in advance for any and all suggestions. Want to cover all areas in next few years while we still have our health. Want to go to Canada, Washinton, Oregon, Northeast coast, you get the picture. Is there a magazine that lists most campsites or areas for overnight travelers. We have the AAA books but they don't list a lot of sites.
