I'd probably "try" the silverado, just so I know how it works, but if everything is setup for the Tahoe, you will likely need to be able to make adjustments to the hitch.

That said, you will benefit from a second friction sway bar on the other side, when pulling with the Tahoe, for that matter probably with the silverado as well.

Even with the longer wheelbase, I don't feel that is going to save you from being pushed around by the bigger trucks. Maybe with the second friction bar, but not just the wheelbase alone. Just a feeling though, as I have nothing to compare it to at this point in time.

For me, with my tahoe, pulling almost the same unit, the second friction bar was a big improvement. Enough for my wife to even comment on. I also have found that if safe, moving over a little in the lane away from the semi's that are passing (or that I am passing), is very helpful to negate some of the "pushing" effect.

My first RV was a 20 foot TT weighing 4100 pounds wet and loaded. I started out towing it with a Silverado 1500HD crew cab short bed. Later on I upgraded to a GMC 2500HD crew cab long bed.

The extra length made a big difference in "porpoising". The improvement in towing was much more than I had expected.

I am a fan of long wheel bases in the truck.

I never thought of using a second friction sway bar. Good thinking out of the box.

Update after a couple months of towing. Vastly better sway control with the Silverado. Amazing how a longer wheelbase can improve the control.

To answer some questions above the Silverado has D load range tires while the Tahoe has C. Total weight of Silverado and trailer was 11,100.

BUT, just got back from a trip through South Dakota and the Black Hills. I really missed the power from the Tahoe. Silverado was struggling to pull the grades without overheating tranny. Even had to stop once to let it cool down. Only able to make about 25-30 mph going up the mountains. Hate to say it but it looks like I will be going back to the Tahoe simply due to the power issue. In the end will probably be saving up for a new truck. Hope folks can learn from my mistakes!

And TPC thanks for the advice. Will pursue a second friction bar in the short run. Great idea!

I feel like the biggest difference between the two vehicles has to be gear ratio, not necessarily "power". But a quick google lead to some complaints on certain silverados with the 5.3 and 3.08 ratio that had to do with a lack of power.

How hot did the tranny get? Do you have the auxiliary trans cooler that mounts up front directly in front of the radiator? I believe all of these trucks have a built in trans cooler, but not all have the additional one up front, which is a huge help.

Also note that because the built in cooler is cooled by the engine coolant, if your engine temps start climbing above 210, your trans temp is going to climb as well. Thats is why I think having the additional cooler up front is such a big help because that is being cooled by direct airflow.

Have you considered changing out the diff to a better towing ratio? It would be a lot more economical, unless of course you need a reason to buy a new truck!

Yeah, I reckon it's wrong to say power in that instance. It simply is the gearing causing problems. Both vehicles have the heavy duty oil cooler but no additional tranny cooler. Pulled over to rest when tranny hit 230.

Would love to change out the diff, but with it being a 4x4 would require the front end to be done as well. That puts a big price tag on a truck that's only worth about 10k.. So good reason to get a "new to me" truck!

You can pick up the OEM additional tranny cooler for right around $100 I would guess, at least I think thats what I paid way back when. Comes with transmission lines and everything, but the lines will be hard lines. It is, without a doubt, a royal pita to fish a hard, pre-bent tranny line from the front to the back of the truck or vice versa. Even more fun is trying to connect them on the top of the tranny by feel, since you can't see up there.

Probably worth every penny of having it done at the dealer. Satisfying to do it yourself and save some $$ but I would plan on a weekend spent, or least a full day.

Will drop your tranny temps by about 25-30 degrees. I would have stopped around 230 myself, maybe earlier.

A SUV might not have the payload capacity as it has a heavier curb weight. Before you decide look at payload capacity on door pillar. Drive train being equal truck will have longer wheel base and higher payload capacity to absorb hitch weight and all passengers/cargo in bed
