IMO, wheel base is a major component to safe towing with peace of mind. Some tow with short WB set up very carefully but it is not optimum. A 1500
Silverado, ideally long bed, with the 6.0 engine & 3:73 rear end & the other towing options should be a good TV.
Chevy trucks are sprung soft for a good ride. This is good for the AS also but you will need some weight distribution. Spring bars are part of the WD system. Depending on their size, some "spring" more than others. Their job is to take weight off the rear of the TV, distribute it to the trailer & the front of the TV, and still flex. The thicker the bar, the less the flex. Less flex makes is hard on the AS, it likes a soft ride. I'm no expert but would think you would need maybe 800# bars with a 1500
Safe & happy travels. John
