I figure many of you pull your cars so you may have some input for me on pulling. I have a 2015 GM express passenger van. 3500 with 6.0l. I also have a 2015 Keystone travel trailer that is about 7,000lbs fully loaded. I’ve been pulling this setup for three years and feel very comfortable doing so. I do use a weight transfer hitch. Most of our camping is 3-4 hour drives with some at 6-7. However I’m looking at doing a 13 hour one way trip late this summer. I will have some elevation to deal with. One thing about the van as opposed to the truck is the vans only have the option of 3.42 gearing as most the trucks I’ve seen are 4.10. So I’m under powered compared to the trucks of the same set up. I had the transmission fluid and filter changed at 50,000 miles. It was darker than I would have guessed not terrible but I could see the discoloration. Pulling the camper on this trip is going to save me about $200/day for a 14 day trip. However if I burn up my transmission then all is lost and then some. Am I just being over concerned or should I rethink this? I’m well under the pulling capacity of the vehicle. Thanks in advance. Chad
