First Time RVer. Help a brother out!

Good morning to all. Thanks for taking the time to read my post. I am about 3 months from hitting the road to California from Texas. I recently bought a 2014 RAM 2500 Big Horn to pull an RV, or Camper. Not sure what the preferred nomenclature is in the RV community. I am looking for a fifth wheel with a toy hauler, but with the plethora of makes and models, it can be a bit challenging to decide what to buy. I figured I'd stop by a dealership and seek assistance, only to find that the sales team will try and sell you what benefits their dealership and their pocket. So, is there a specific make or model that I should stay away from??????

Thanks in advance for your time.
