Am looking at a Reflection 27RL with a GVWR 9995 lbs., dry weight 7998 lbs., and hitch weight 1516 lbs. I have a 2010 Chevy Silverado 1500 4WD Ext cab LT with Vortec 5.3L V8, HD cooling, 3.42 rear axle ratio, Z85 handling and trailering susp., and 18" on/off road tires. The book says it can handle Max Trailer Weight of 9600 lbs, GCWR of 15000 lbs, and kingpin weight of 1500 lbs. Big enough?
