Good evening everyone!

My wife and I are looking to purchase our first RV to take our kids camping. We were suggested Grand Design from several friends. A little background, my family consists of myself, wife, 3yo and 1yo. Total weight for us is about 425 pounds right now. No dogs or any other pets.

Our tow vehicle is a 21 Ram 1500 with the 5.7 eTorque and 3.92 gears. Below are the numbers of my truck taken directly from the stickers on the door;
GVWR 7,100
Curb Weight 5,596
GCVWR 17,000
Towing 11,400
Payload 1,504
GAWR Front 3,900
GAWR Rear 4,100

We were instantly drawn to the Imagine 2400BH (7495 Gross; 5725 Dry; Hitch 505) We also like the Imagine XLS 23BHE (6995 Gross; 5325 Dry; Hitch 504), but definitely prefer the 2400 BH.

So, what is the realistic loaded tongue rating of the Grand Design's? It may be a loaded question and I'm sorry if it is. Based on our current weights and figuring in 100 pounds of cargo in the truck, 100 pounds for WDH, our max tongue weight to be within payload would be 850 pounds (11% of 7495), that would still give me 29 pounds to spare. Am I being overly ambitious thinking the 2400BH is doable? Or do I need to be shifting my focus to the XLS23BHE based on the numbers? Thank you in advance!
