Hi, I'm about to buy a 2005 Toyota Highlander (Limited V6 4WD), and want to install a tow package. Any suggestions about what kind to get and if it's significantly better to do it at a dealer versus a Uhaul? Also, are there any, suggested performance parts / upgrades I should consider installing (e.g., to improve its towing capacity, which seems a bit modest -- esp. at higher elevation, and I'm nearly at 6K feet)? Thanks!
