I think the answer is probably "Yes", and I'm certain that your stopping and steering performance will be better.

The WDH keeps the tongue from unloading the front axle. Tongue weights run higher than we expect sometimes, particularly for people hauling extra batteries up there. Some have tongue weights that are more than 750#, but most of us are in the 500# neighborhood.

Here's the truck scale experience where one of our members found that his 480# tongue added 700# to the rear axle and took 220# off the front end.

Truck weights (with me @ 185 lbs):
Front Axle 3320
Rear Axle 2560
Total 5880

With Trailmanor hooked up (65 lbs. of WDH are included):
Front Axle 3100
Rear Axle 3260
TM Axle 2920
Tongue 480

Also, here's a site I found with lots of good info. This link is to a 2010 owners' manual where it says on page 5-59 that the maximum tongue weight without a WDH is 600#:
