Then you'd better plan on being closer to 16K than 14K when you're loaded and ready for travel. That's why we kept saying that the safe sizing method was to use the trailer's GVWR as its loaded weight.

Just to clarify: the dry weight of this trailer is 13400. With the options we added, it will be around 13800 (we will weigh for exact GCW right after picking up the trailer). On our trip to Oregon, will not have any belongings in the trailer - we will rent a UHaul and have everything that we would put in the trailer in it. At 19%, the pin weight will be 2600. This will put us well under GAWR (rear) but put us a few hundred pounds over the GVWR. I'm comfortable with this esp. given that, outside of the trip to Oregon, will not be pulling it much after that.
We will also be following the recommendation (thanks again) of getting "E" rated stock tires (and possibly 4.10 gears depending on performance from dealership to home).

LT 265-70-17 load range E and no less. LT 275 70 18 would even be much better at 3750lbs capacity as I have on my SRW. I am OK with my BC by Heartland and dought the Redwood model as being much harder to pull but you need to make sure of the axle capacity with 110lbs air pressure tires. If not the pin will be severely loaded for a SRW truck. Many manufacturer get away with 6k axles and load the pin, Jayco and FR comes to mind. Others now use 80lbs load E tires with 3450lbs capacity and are severely loaded for the air pressure and can only heat up the tires.
My neighbour here also tows a 39ft Heartland with his Ram 3500 SRW with 265-70-17 tires.

Thanks for the info caissiel. Aside from the increased load capacity, are there other pro's and cons of choosing the LT 275-70-18s over the LT 265-70-17s. Fortunately, it looks I would be able to keep the same wheels if I do go with the 18s.

Also, the 285-70-17s that I have now are "D" rated for 3195 lbs. The 265-70-17s are "E" rated but have the same capacity at 3195. What is the difference? Improved ride? Better fuel economy? other?

Also, would you still recommend the Hypertech Max Energy or another product?

Thanks.

At 80 lbs and load range E. It is the best for stability. Your wheels should be rated for 80lbs. Load D tires are much cheaper and have softer sidewalls. 20 inch tires are next in line with greater capacity tires w/load range E rating. I found only 4.5% difference and was capable to programe it in. I have great power and performance with my hypertech Max energy and it allows change of tire size while Econ. will not.
