square body towing

Who tows with there square body dually. My baby momma thinks gas will kill her when she uses my truck to tow her a horse trailer. Said its tome for her to save up for a truck . Lmao I'm like my carbed dually will do the job just fine. Any advice

Not sure how large of a trailer she has but, we pull a 48' enclosed racecar hauler with triple axles and a full lounge, loaded with crap with out 2000 c3500 454/auto. Driving speed limits we get around 12-14 hwy! Not too bad considering it's about the same empty around town.

Maybe she just digs your rig so much, she has been inspired to have one all to herself?
