Agree with the others. A 32' rig with a family is in 3/4 ton truck territory. Some may get away with towing them with 1/2 ton trucks, but those are usually heavy half tons like the Ford f150 with max payload package. I think those can be had with a 2000 lb payload rating.
Based on the way your initial post was written i suspect you had a feeling this might be the case. Questions like this seem to get posted very frequently. Good job for checking into things before you buy a vehicle.
You either need more truck or a smaller, lighter trailer in my opinion. Good luck.
