I understand how disappointing this can be. You did mention something about having it delivered which would remove the towing factor out of the picture, at least for now.
When I first brought my TT I didn't have a TV so I borrowed my sister's Yukon for almost a year before I got a truck. Before I brought the truck I thought I had found the right TV more than once before I was given the sad news that I was off the mark with my choice. In the end it worked out and it will also work out for you too. Don't give up.
Be aware of sales staff using "dry weight" numbers in the sales pitch.
Great choice for "Living within my means" and camping for one...
