I'll say go for it too. You may be a bit slower than you like, but the Tahoe will get you their safely. Assuming balanced et correctly!
Now my cavete! 4 kids.......them kiddos grow at 10 lbs or so per year....by the time they are adult sized teens, that Tahoe will have lost any and ALL excess payload you currently have. An eight lug 25/35 series rig need to be on the horizon, just from a payload standpoint, to pull a trailer that size. My family of six weighed in at around 1200+/- lbs when my kids were adult sized teens. Been there done that. My trailer was upwards of 7000 total, 600-800 hitch weight and 25' long. We loaded upwards of 3000 lbs into my SW crew cab 3500 all inclusive people, he, dogs, bikes canoe etc.
