Go with the class III, 2". Much easier on the van to load the trailer. Take your time to load it with 10 to 15% of the trailer weight on the tongue. & stay under the max load rating. "" Trailer Loading The way you load the trailer can determine how easy you can tow it. While loading, keep in mind that the tongue weight should be 10% to 15% of the overall trailer weight. One of the main causes of trailer sway is not having a large enough percentage of trailer tongue weight compared to gross trailer weight. To help prevent the trailer from swaying back and forth, a few things can be done. Try placing heavier cargo in the front of the trailer, ahead of the trailer's axle. Also center the cargo left-to-right and use tie-downs to keep the load from sliding. "" The safety thing you mentioned will pay off over time ! Most auto parts stores have the trailer wiring kits "on the shelf".
I've done some looking. I'll need of course the receiver, then the powered wiring kit, my old mounts won't work so i need that too plus a new ball because the stud on the old one is too small. By the time I'm done I can go to the neighborhood welding and hitch shop and for about a hundred bucks more he'll do all the work putting it in. I'm thinking to just do that and give him the business. I suppose his family has to eat too. If I'm lucky maybe that will include some morning donuts. Thanks for all the advise. I'll go with the 2" either way I go having it installed. Half my trouble is getting the time to do things and now if I get some time I'd rather go get some firewood after my pile took such a hit from this last winter. I've never gone and collected firewood in the spring and summer. Along with a new hitch, I ought to stock up on bug repellent too.
