Thank you everyone. My trailer is a fiberglass Topcap covered trailer with usually 2 snowmobiles so within the towing limits of most mid sized SUV's. Interesting gas mileage heinz66, but that makes sense. The smaller engine is working a little harder. I went from an '04 diesel Excursion with the 6.0 which was overkill when it was running. ( you may have seen me on the shoulder of highway 2 in northern Wisconsin many times when it wasn't running ) I went to the Suburban and thought that was a small suv compared to the Ford but it worked pretty well. I'm still on the fence, and I appreciated the input from everyone. I'd love to buy a new suburban but I can't believe how much money they are! I'll check out pick ups, looks like some better deals on them now. I'll let you all know what I end up with. Until then I'll continue driving myself insane over what to get!!!
Again thank you for the input
