Yes it is a 4X4 and it's at 80,000 miles. Maybe they are looking through the window to see that. Yeah we are not looking to sell at all. The front hitch came with the tow package her Grandpa got. The only upgrade as he was going to use it to tow his fishing boat. The last guy was up to a $10,000 cash offer and my wife looked like she was interested. I told the guy the only thing we could take from him that day was his phone number. When we were alone I explained to my wife that the last place we want to be is the current car market because we would just be looking for a replacement as she drives the Tahoe daily even though we have two other cars. Plus you never trust the person making the offer to be honest about market value. Thanks for the replies!!
