Weight Distribution Hitch Question

i would try it without one first and see how she rides. i have a 33ft TT. i pulled it with an f150 with WDH for about 4 months. recently updgraded to a f250 gasser. i already had the the WDH so i haven't even tried to tow without it because its so comfortable. why tinker with a good setup and it only takes a couple of minutes to hook up or unhook. one thing i did learn that i hadn't thought of before concerning the weight distribution. my f250 is 2 wheel drive. i park the TT a home in a grassy back yard area on a slope. the first time i hooked up to tow the TT i hooked up WDH completely. i had a problem getting traction going uphill. new to me because my f150 is 4x4. then it hit me. duh! the WDH is moving weight off my truck tongue so it was too light to get hill traction. next trip i hooked up TT on ball hitch backed up and pulled TT uphill to my driveway with no problem, then hooked up WDH in my driveway.
