Hey all. Not sure if this is the right forum for this, but I'll give it a shot. I have a 2012 Silverado 5.3L Z71 with 6L80E tranny and KC4, K5L, and KNP RPO codes (transmission cooler, heavy-duty oil cooler, etc.). I have the 3.08 differential (I know...). This gives me relatively low specs of 1,600 lb payload, 7,000 lb GVWR and 12,200 GCWR. In addition, I have a weight-distributing Class III hitch rated for 1,100 tongue weight and 10,500 trailer weight, axles are rated at 3,950 pounds each, and LT tires with 125 load index, so I'm good in all those areas.
I'm shopping for travel trailers for my family of four. Our ideal model (2018 Bullet Crossfire 2200BH, for those interested) comes very close to maxing out my truck's specs. The trailer is 3,975 lbs empty with 425 lb tongue weight. Seems that the rule of thumb for RV folks is to assume a working tongue weight of 10-15% of loaded trailer weight, which includes the propane and battery. Assuming 1,000 lbs of gear in the trailer and using 13%, that's 650 lbs on the tongue. Adding 600 lbs of people and 300 pounds of gear in the truck puts the payload with loaded trailer at 1,550, which is within 50 lbs of the rated max. Also puts the truck and trailer combined weight at 11,925 pounds which is a cushion of only 275 lbs from the 12,200 GCWR.
I'm wondering what peoples' experiences are towing a travel trailer with a load this close to the rated max. I know that the 5.3L and 3.08 gears means it'll be sluggish, especially up long grades. While certainly not ideal, I think the powertrain is probably acceptable. I'm more wondering about safety and stability- the truck getting pushed around at that weight, especially with the wind-catching shape of the travel trailer. Buying a bigger truck is not an option - buying a smaller trailer is. What do you guys think about this?
