2011 Tahoe Pulling Passport 2650BH Travel Trailer - Advice

I tow a 32 foot with our 2004 Tahoe. It's got a 7500lb towing capacity. HD tow package, trans cooler, WD hitch, sway, etc... I run about 5800lbs loaded and it tows fine. It's not ideal but it's ok for now. I do plan to purchase a 2500 HD next year due to comfort for longer more difficult trips but I stay in my area mostly and it does fine. You should make absolutely sure you have a trans cooler on that dude before you go too far though.
