Ok, I'm new to this site, but not new to campers. I know this topic has been beaten to death on multiple sites and it is still clear as mud to me.
I have a Chevy Silverado Ext. Cab 4x4 with long bed and the Duramax/Allison set up. I also have an 9'9" Elkhorn camper.
Curb weight of my truck is 7220 lbs.(just came from the scales and I account for 215 of the 7220). For purposes of easier math, we are taking me out and rounding to 7000 lb curb weight.
GVWR - 9200
Added different tires which should yield an additional 400 lbs to my max load over the stock tires that were used to calculate 9200
In theory, I'm up to 9600 lbs
My GAWR RR is 6084 lbs
I'm trying to figure out how the payload (GVWR + added max load from new tires - Curb Weight OR 9200 + 400 - 7000) of 2600 lbs relates to the GAWR RR of 6084 lbs.
My camper has a dry weight of 2910 lbs. I'd like to move up to a 3400 lb camper (smaller in length, but offers a slide out). Based on average increase to calculate a "wet weight", I'm guessing I'm around 4000 lbs already. This means I'm looking to jump to roughly a 4400 lb total weight solution.
Without considering the GAWR RR, between the curb weight and an estimated 4000 for the wet camper, I'm already over my payload by 1400 lbs (not including passengers).
I have had this set up for 5+ years and I'm getting a pretty decent ride. I will be adding sway bars shortly from Torklift to clean up the side to side in windy situations, but the math has never added up. I also tow a 20' Alumaweld, but my GCWR is 22000 lbs and my boat loaded weighs less than 3000. Not concerned with what I tow, only what I'm hauling.
Bottom line...how much should I rely on Payload vs GAWR RR?
Thanks in advance to anyone that will "weigh in" on this dilemma....pun intended.
