I have a 2015 Silverado 1500 Z71 double cab 6.5' bed with 5.3L and 3.42 rear end. The payload sticker says 1756 lbs. Currently I have a Jayco 23FB travel trailer. I race motorcycles and the last couple years I have loaded the race bike and most of the associated track gear in the bed of the truck and towed the travel trailer to the track. I now have a second bike that I take to the track. it's not easy getting both bikes in the bed of the truck with all the gear but it's possible.

With the jayco trailer I am well under the GCVWR but with both bikes, gear and tongue weight in the bed of the truck I am a couple hundred lbs over the GRAWR and obviously over the payload number and GVWR. I have a well setup WDH and both the trailer and truck sit nice and level and I never had any issues with handling or trailer sway.

I am taking delivery of a toyhauler in March that is 5 feet longer and about 2000lbs heavier than my current travel trailer. Because I know the empty weight and as loaded weight with all my gear with the current trailer, I have a pretty accurate estimate of the weight of the cargo I will be putting in the toyhauler. With the bikes and gear in the toyhauler, the bed of the truck will basically be empty now. With the max tongue weight of the toyhauler and basically empty truck bed, I will be able to get under the payload GVWR and GRAWR on the truck, but the increased weight of the toyhauler will mean I am likely to be between 500-1000 lbs over GCVWR. I could save some weight by not filling the toyhaulers 30 gallon fuel tank until I am near the track.

Because of the increased weight and length of the toyhauler I am investing in a Propride 3P hitch that eliminates sway by projecting the pivot point forward to near the rear axle, rather than the traditional method of trying to "control" sway with friction. I'm not concerned about sway or the "tail wagging the dog", so to speak.

So my question is being 500-1000 lbs over GCVWR but well within axle ratings, GVWR and payload better than being under GCVWR but being over Payload, rear axle rating and GVWR, like I was this past year? Obvioulsy the loading and unloading with the toyhauler will be much easier and having a fuel tank rather than hauling multiple 5 gallon jugs of fuel will be so much more convenient. I am well prepared to see a decrease in fuel mileage also and of course I expect the accleration with the increased weight to be somewhat reduced.

I live in WNY and the racetracks I frequent are in OH and PA. No extreme mountain grades or towing in extreme heat, like in the Southwest or anything.

So over GCVWR but below everything else better or worse than being under GCVWR but being overloaded on the rear axle, payload and GVWR?
