Lot of opinions on this. Mine is based on experience and thousands of miles. We towed for many years with an 01 Dodge Grand Caravan. Our trailer weight was 3,490 loaded and ready to camp. We did install rear air bags. Van did quite well as we traveled from Oregon to Canada and south to Mexico, Colorado too. MPG was about cut in half with trailer. Grades did not slow us as much as head winds. We had the 3.3 V-6 and passed many larger rigs. We did blow a tranny at 84K which extended warranty replaced. Sold the van with 127K. Never overheated. Chantged tranny fluid every season. Shoot me a private message if you have any questions. Pay attention to your factory numbers. You should be fine.
