I did read thru your whole post and can not comment on the individual trailers in question... I'm still running with my first TT I bought brand new back in 2002 and it's still in great condition and all I need.. :)
What I caught in your post was that one of those trailers has a #4700 DRY WEIGHT rating.. What's it's GVWR? I know most folks don't tow a TT to go camping at it's dry weight.. ;)
Going to tow it with a 2016 Chevy Colorado.. While those are nice rigs, and current day V6 engines have a lot of power, I think you will be able to get down the road, but how are you about putting your foot to the floor, 4k rpm + at times and being basically maxed out weight wise??
Not saying it can't tow it.. Just saying that I have done that before, and even for a 100 mile trip, it's not that much fun... Sure, you get to your destination, but I like the road trip part as much as I like the destination.
My TT has a dry weight of around #3600 and it weighs every bit if it's #5000 GVWR, if not a tad over after all these years..
Anyway, towing performance is completely subjective to say the least, from one tower to the other, so you just gotta take whatever responses you get with a grain of salt and decide from there...
Good luck!
