With the purchase of out Convincor 270 the TBSS was at it's tow limit, but did tow very well except for the short wheelbase towing total of 31ft. @016 Yukon XL Denali w/6.2L and 8spped trans. Yukon even gets better MPG around town 17mpg and on todays tow to river trip computer shows 14. TBSS gets 13mpg around town and 10mpg towing. Still keepin the TBSS as our hotrod!
