Need help with comfortable towing weight and length.

If as donn mentioned, you load up the rig, weigh it, if it is at gvw, then you have NO tow capacity! unless you want to tow a trailer with no hitch wt!

There is not a what is comfortable as far as what you are asking. There are a couple of "rule of thumbs" besides staying under gvwr for the truck and trailer......

IIRC max length is 110" wb for 20', then add/subtract a foot of length per 4" of wb.

I use a max trailer weight of 2x the grawr.

Then use the gcwr as a guide per say. Then again, I also had and have a truck where the gcwr is lower than its gvwr! I guess I can not load to gvwr?!?!?!?!?!

BEST max trailer by lbs, is weigh the truck ready to go with people etc. Take the remaining payload to gvwr, divide by expected hw%, and you have max trailer you can tow. So if you have 1000 lbs left over, you have a max 10K ball mount trailer with 10% HW, or 4000 lbs if you tote a 5w with 25% hw! If the tow rating is under these amount, that that is your max warranty tow rating available to you!

You have the GCWR numbers already. Load everything up in the truck like you will normally travel and go to the scales. From there you can subtract scaled weight from GVWR. That is available payload. Or tongue weight for a TT. Also you can subtract the scaled weight from the GCWR. That is how much you have left over for a trailer. Keep a trailers GVWR under the last number and you should be OK on both numbers.

Thanks Mr. Landry.
So i guess my problem is I don't know the tow rating of my truck. I thought that the gvwr is the max truck and all cargo and passengers. Or am I wrong? What is or where can I find the max tow rating.
Again, thanks for the help.

Bottom line is that the gross weight of the trailer should not exceed the tow rating on your truck. No one here is going to tell you that it's OK to exceed any of the truck's ratings. Aside from that, "comfort" is subjective. Only you know what you are comfortable pulling and parking.
