Which WB hitch will I need because I notice they come in different sizes?
Yes, they come in different weight ratings. You want one that is rated higher than what your loaded tongue / hitch weight will be. Give yourself some room for fluctuating tongue / hitch weight. If your ball park number is 700 lbs, you want a hitch rated for at least 800 lbs.
The reason for going with a higher rating is, tongue / hitch weight is not a constant number. It goes up and down during every trip. Different things get loaded in different places, holding tanks get filled up, groceries and water get used up, etc. Also, depending on location (in relation to trailer axles), your holding tanks can have a significant impact on your tongue / hitch weight.
I have a galley tank located up front. It can add a couple hundred lbs to my tongue weight. My fresh water tank is behind the axles. It takes weight off the tongue. My dry hitch weight was advertised at 880 lbs. During a trip, my tongue weight can be anywhere between 975 and 1200 lbs. I have a BlueOx Swaypro hitch, rated for 1400 lbs. Their 1000 lb hitch would not have been enough, and, the next one up was rated at 1400 lbs. I believe they have one rated at 800 lbs.
