I'll be towing a 2001 Santa Fe with a 2002 Hyundai Santa Fe. I have a sway bar and electric brakes on trailer. I will also be replacing the shocks on the TV asap as they are a little bouncy. Towing it home from the RV dealer was a breeze, but I know that if we want to do mountains, etc we will need to hitch up to the Explorer Sport. I would like to take my bikes but currently only have a rear door bike mount and I'm afraid that adding two bikes will put too much weight on the hitch. Thoughts?
