The trailers you are considering will weigh 7000 to 8000#'s loaded up ready to camp. My Bullet 295BHS started life at 5650# dry and now weighs 7200 to 7500 depending on how much water I add before I pull out. That's with 2 kids and a dog.
The tongue weights on these will be 1000# +. Mine is at 1100 to 1200#'s measured with a Sureline scale.
Most 1500's don't have the payload to carry that much tongue weight, passengers, and stuff in the bed. Do yourself a solid and get a 2500. You won't regret getting the proper tool for the job.
