I had asked a question of the group about the suitability of the Jeep Pentastar V6 for towing. I got many thoughtful responses and very much appreciate them all.

Yesterday I went to my Jeep Dealer and learned more, plus test drove both the V6 and V8 versions. For what it is worth, this is what I found.

1. They are very willing to let me bring my trailer down and take it for a test tow with the V6.

2. The 5.7 L V8 is a newer design, first available in the mid 2000's. I had thought it was one of the old ones just updated. But no, it, like the V6 is a "modern" engine.

3. The test ride (not tow) with the V6 was nice, but it had to downshift a lot to get the RPM's up to go into the power range (opinion of course, but that is what it felt like). Shift points when floored were 6000 RPM.

4. The 5.7 L V8 positively lunged when floored. The burst of power was quite incredible. Without a doubt it would be a very nice engine to have.

I now feel, with all of your advice and help, that the V6 would do the job, have a good long life, and I would probably be happy enough with it. But once I drove the V8 I saw that it would simply be an effortless engine to tow with here in the mountains of the West. I think the V6 would work harder towing, and probably not have any better gas milage than the V8. With 4 cylinder deactivation on the V8, the highway milage should be close to the V6, solo.

I have not made the purchase yet, but when I do the V8 will probably get the nod.

And, once again, my thanks for all of your input. It was most helpful to me. This is a wonderful group to belong to, and I hope that the fact that the question was a bit "off topic" vs. GMC motorhomes was OK.
