Chevy V6 4.2 Litter Engine

My dad is looking to purchase a 2004/2005 Trailblazer Ext and is trying to decide what engine to put in it. He has a 21', 3500# travel trailer that he pulls from end of December to mid April (yes he is retired). Currently he has a Chevy Astro van with the 4.3 litter engine in it and he is happy with the preference of it, but he is trying to decide what engine he should get in the trailblazer. The dealer is telling him that all he needs is the 6 cylinders but I am worried about the engine longevity. So I am just looking for a little advise

Rob the engine used in the Trailblazer is an inline 6 that develops 90% of it's torque at 1600 rpm. If the dealer offers the 24 hr. test drive have your dad bring one home, hook up the trailer and decide if the 6 has enough "umph". All have trailer hitches however doubt they'd have the brake controlled installed so he would have to take that into account. I would suggest something other than the stock 3.42 axle. Perhaps the 3.73 as an overall compromise.

I have a 25' Wanderer Glide-Lite trailer. I used to tow with a GMC Safari (same as Astro) and found it to be lacking when facing stiff head winds on the freeway. I now have a Yukon with the 5.7 and towing is much better. Both vehicles had/have the 3.73 axle. I'd recommend he het the 5.3. No one was ever sorry they had too much power when towing! Besides, trailers have a way of "becoming" too small and if he trades up (like I did) the six isn't going to cut it.
