Wow, great response from everyone and I really appreciate the respectful input from you all. I have been on other forums (other topics) and always seem to get a cluster of sarcastic and/or PIA people posting and even taking over my thread but you all have been very helpful.
I am not surprised that most everyone recommends the 250 but am a little taken aback by the fact that it seems the 150 would struggle (my interpretation from the posts) and/or be too small to pull it.
Every time I tow with my camper I feel like a schmuck for putting my family inside and risking all of our lives in the process. We don't camp more than 4 hours away and have only been going about 5 times a year, but it still puts a strain on the LTZ. If I get her rolling on flat ground, she will haul it down the highway pretty good. Of course it has weight distribution and sway bar control on the hitch too, plus auto leveling on my truck. But it still down shifts hard on hills and I can really feel it whip me around.
I really didn't want to buy my next vehicle based on the needs of the camper, since we only go a few times a year, but it also doesn't make sense to own 3 vehicles right now. I was really hoping to find something that serves my non camping needs and while it may not be the ideal tow vehicle would still easily tow the camper safely.
Guess you cannot have it all. Thanks for the input and please keep the comments coming as I appreciate the different view points.
