2011 Tahoe Pulling Passport 2650BH Travel Trailer - Advice

IMHO Clint, you are going to be too close for comfort with this. For one thing don't assume that the 4800 lb. dry weight is accurate. Weigh it yourself. Secondly, even if that's accurate it only leaves you with 400 lbs. of carrying capacity to reach the Tahoe's limits.

Lastly, and perhaps most importantly...just because the engine is rated to tow that much weight, doesn't mean the suspension can hold a trailer that heavy.

It's the manufacturer's dirty little secret and very misleading.
