Welcome to our group !! Plus 2 with Jim , I towed ours with a ;350 SRW and lets just say someone got a very nice 8 month old truck when I went to a Dually. Especially with the RL, as it has a heavy pin weight. Tows great because of it but is heavy.
As others have said, if you're going to be traveling G tires and wheels and Disc brakes are must haves.
Get a good extended warranty in with the deal and you should be good to go. You might also consider having a NRVIA certified inspector do a pre-purchase inspection if there is one near the coach.
You'll love the RL. We have towed ours more than 15k miles in a little over 2 years and it will see another 4-5k this year. Planning on full time next winter if all goes well.
