@jthorn75 do not waste any money upgrading your truck. You have a tow capable RAM.
FOLLOW THIS FORMULA AND ONLY LOOK AT TRAILERS IN THIS RANGE.
GVWR minus Payload equals base weight
GCWR MINUS base weight equals max cargo/passenger/trailer.
Your GVWR is 6900
Your GCWR is 13900
Your payload is 1594
Your base weight is 5306
Your cargo/passenger/trailer is 8594
So...now is where you need to make some calculations.
8594 is the max everything you add to your truck can weigh. So RAM gives an allowance of 470 pounds when they figure max trailer weight at a 10% tongue weight in the charts.
I will assume some numbers. Family of 4...575 pounds...some cargo...250 pounds.
8594 minus 575 minus 250 is 7769
7769 is trailer and tongue. So your magic number is 6900lbs
Since you said you never did this...you want to stay under that number. If you had some experience, you could make the number 7500...but that would not be a fun drive
Now with this number 6900....this is Camper GVWR...DO NOT LET THE SALESMAN sell you a 6900 inside weight trailer...you will be over your rating. You have to focus on GVWR.
And you want to stay under 28 feet...24 to 26 will be the sweet spot.
Make sure you explain 6900 and 28 feet to your wife and salesman.
Cause as soon as the salesman shows her the 32 foot 9000lb camper...you got to get a new truck
