How to Determine Tongue Weight for Motorhome Towing Trailer
Question:
I am thinking about using a weight distributing hitch on my motorhome. I am not sure how determine the spring bar rating because of the long distance between the RV rear axle and the hitch about 11 ft. Without a WDS, a tongue weight of 200 lbs puts about 500 lbs on the RV rear axle and takes 300 lbs off the RV front axle. Do i use the tongue weight, use the 500 lbs added to the RV rear axle, or some other basis to determine spring bar rating since the fulcrum distance 11ft is so large? Thank you

Tongue weight is going to be the loaded tongue weight of your trailer plus the weight of any cargo stored behind your rear axle. You don't want to get caught up in changes to the weight on your axles with the trailer attached. Once you find this you will be able to select the correct weight distribution hitch. Also, you need to make sure that the hitch on your motorhome is rated for use with a weight distribution system.
For a quality WDH that is widely considered the best I recommend choosing the Equal-i-zer system. You can choose from the following based on your tongue weight:
-Equal-i-zer Weight Distribution System w/ 4-Point Sway Control # EQ37040ET (tongue weight up to 400 lbs)
-Equal-i-zer Weight Distribution System w/ 4-Point Sway Control # EQ37060ET (tongue weight range 200 - 600 lbs)
-Equal-i-zer Weight Distribution System w/ 4-Point Sway Control # EQ37100ET (600 lbs - 1,000 lbs)
-Equal-i-zer Weight Distribution System w/ 4-Point Sway Control # EQ37120ET (800 lbs - 1,200 lbs)
-Equal-i-zer Weight Distribution System w/ 4-Point Sway Control # EQ37140ET (1,000 lbs - 1,400 lbs)
-Equal-i-zer Weight Distribution System w/ 4-Point Sway Control # EQ64FR (1,200 lbs - 1,600 lbs)
