pulling a 29ft travel trailer with a 2010 avalanche??

You will be just fine just don't load the bed with a bunch of gear put in all in the trailer as payload will be your only concern.

We have a 2012 Avalanche. We pull a 27QBSS, one long slide, actual 31'8". Dry weight 4201 GVWR 5993. We have no issues pulling. We also pull our 20' princecraft boat behind the trailer sometimes. We have a good weight distribution bars Enjoy!

The dry weight is probably low, and if you have a 1/2 ton that is a fairly soft suspension for such a long trailer. It would handle fine under normal circumstances, but have an emergency stop or drive on crappy roads and the 1/2 ton isn't enough in IMHO.

Your more than ok and a good set of weight distribution bars will help keep everything nice and level.

if you have the 2500 you are ok. If they still make or made it that year.

Since you are from the "Dena" the answer is yes . What you need to do is see what the towing capacity is for the truck . What motor you have , etc . But I dont see you having a problem .
