We are considering a new tow vehicle.

We now have a 2005 Suburban 2500 w/Vortec 8100 496 cu in V8 (325 hp at 4200 rpm and 447 lb·ft of torque at 3200 rpm) and 4.11 axle ratio. It is rated to tow 12,500 lbs and our trailer is a Keystone Outback KRS 23' with the garage in front where we store an 800 lb. HD Road Glide. The trailer is 7500 lbs. loaded. The tongue weight is a little close to max due to the bike in front.

Our Suburban is almost pristine, very well taken care off and just had a new cam and lifters installed at 200K miles. Maybe it's time to get a newer tow vehicle, maybe not.

POSSIBILITIES:

2015/16 Ford Expedition w/3.5L EcoBoost® V6 - 365 @ 5,000 420 lb torque @ 2,250 - tow capacity 9200 lbs

2015/16 Chevy Tahoe w/EcoTec3 5.3L V8 - 355 hp 383 lb torque - tow capacity 8600 lbs. w/3.42 axle ratio

2015/16 Yukon Denali w/6.2L V8 - 440 hp 420 lbs torque - tow capacity 8400 lbs.

QUESTIONS:

What will the towing experience be with any of these new vehicles compared to our "old" Suburban? The tow ratings are much lower but there is 10 years of newer technology to consider.

How can they get that much torque/tow capacity from the Ford? It seems like a less substantial vehicle although I haven't checked the weight.

Why does the Yukon Denali have less tow capacity than the Tahoe? I believe the axle ratio is higher but the engine is larger ...?
