Congratulations! My wife and I love our 29M, we have all the bells and whistles too! I don't know the measurements but we have a steep driveway and the hitch scraped every time we went in or out. I ordered a pair of swiveling hitch skid wheels from Amazon and that cured the problem. Took about 15-20 min to install, now we don't worry about steep anything! If you go with the skid wheels they need to be greased before use, I used waterproof marine grease. I hope you will enjoy your coach as much as we do!!!
