Re: new to RV new to my grand design reflection

[grant65]

Looking at a 5th wheel 2015 Grand Design Reflection 337RLS (2090lbs pin weight). Will my 2018 4x4 crew cab chevy diesel pull this RV? Trucks says max 5th wheel is 13,500. I'm just getting into the RV scene and like most people find out the RV dealers don't know and the vehicle dealers don't know either. Truck says my combined weight of occupants and cargo should not exceed 2373lbs, truck has 245 tires. My calculation say get a smaller 5th wheel maybe a 303RLS (1660lbs pin weight). Am I on the right track? air bags?

As I understand it

2373# is your Payload, that is everything you can put on your truck.  Any gear and occupants other than yourself counts toward the payload. 
2090# hitchweight, is an unloaded trailer.  Nobody leaves with an unloaded trailer
This gives you 2373 - 2090 = 283# worth of occupants and ALL your gear, water, everything.
Long story short, you need a lighter 5th wheel, or a bigger truck

ALSO, plan on being closer to the GVWR weight of whatever 5th wheel  trailer you are looking at, and plan on 20% of that as pin weight (or part of your payload)

The 337RLS has a GVWR of 14,000 lb.  If you use that number, and you should, for calulating the pin weight of the trailer, you are at 2800 lb of pin weight minimum.  If the trailer is a bit more than the 20% (calculated above), say 22% or 23%, now you are at 3080 lbs or 3220 lbs respectively.  The bottom line is that is only the pin weight, I've not counted passenger(s), other cargo, about 175-200 lbs of hitch weight.  Anything and everything that goes in or on the truck counts against your payload numbers (2373 lbs), so you could very easily be 800-1000 lbs overloaded on your truck trying to tow that trailer.  Bigger truck or smaller trailer is your best answer.
