With a large trailer behind a motorhome you are also going to find once you get into a site you are going to be out of position to easily reach the services. Most RV sites have the connections to the rear third of the sites, which is the most convenient location to serve the multitude of different types of rigs. With a long trailer you are going to have the connections to your RV in the front third of the site, making long cords and hoses a necessity. Not a deal breaker by any means, but an inconvenience at the least. Also, you will not be able to easily use a back in site since you will have to unhook the trailer and jockey it to it's parking location before you can back into most RV sites. Even if you are a great backer-upper you will find many campground roads will just not offer enough maneuvering room to back a large trailer and a Class A rig into a site.
