First, check your hitch rating. You will likely need at least a 10k rated hitch. Also check your vehicle's gross combined weight limit. The weight of the coach (loaded, full of fuel and water) PLUS the trailer (loaded with toys) should not exceed the combined weight limit.
Second, check what electrical hookup the coach and trailer have. They will need to mate-up so your trailer will have lights and turn signals.
Third, does the trailer have electric brakes. I would assume it does. The coach will need a device that controls the electric brakes on the trailer. If your coach has the device installed, then you're good to go. If not, then get one installed.
We are about 72 feet long when the Avalanche is hooked onto the coach. Generally, when entering a campground the Avalanche gets unhooked right after registering at the office. Rarely do I drive to the RV parking spot with the Avalanche in tow. If your coach will fit into the RV spot, then you're good. All RV parks have a parking spot for your toad and most have a "storage area" where you can park your trailer. Some RV parks have spaces long enough to leave your trailer hooked onto the coach.
Watch your cornering... especially right-hand turns. If you have access to a large gravel/dirt lot, then take your coach there with the trailer hooked on and make the sharpest turn in both directions that your coach's steering will allow. Make note of the rear coach tracks and where the trailer tracks are. In my case, the rear tires of the Avalanche actually go outside the coach's track. That means it's not enough to clear signs and walls with the rear of the coach. I have to ALSO be a bit wider so that the Avalanche will clear the signs and walls.
Never ever be in a hurry in tight maneuvering situations, i.e., high traffic areas, sharp corners, etc. Recently I held up traffic behind me for 15 minutes at a 4-way stop intersection waiting for traffic to clear so that I could make a wide right-hand turn. I had to cross the oncoming traffic's lane to make the turn. In fact, I had to swing way out into the bike lane on the far side of the oncoming traffic's lane! One guy behind me was not happy, but I knew as many cuss words as he did. lol
There's more... but not now.
