New to camping and towing, But upon research I assume this is a good fit. New 2018 Ram 2500 6.7L Diesel max payload 2440, max towing 17260. TT is a 2017 35' 6800 dry weight, listed tongue weight 700 l...
I have the same truck and similar sized trailer. As stated, you will be golden.
The Rams do have an artificially low payload but you will have plenty of axle and tire rating for what you want.
There are plenty of lightweight trailers of hat size too. Mine is 34’ with 2 slide outs and is only 6400lbs dry. Loaded up, with 2 kitchen sinks ;), we are 7800lbs.
