One issue you might run into is the ball size. Your 7000lb trailer probably has a 2" hitch ball. Most WD hitches come with a 2&5/16's ball. I have seen WD setups use a 2" hitch ball, but they are not the norm.

I would load up the entire rig and take a look at how it sits before investing in the WD hitch. As long as your suburban and trailer sit relatively level you should not need a WD hitch - although they do make quite a difference. Same comments on the sway control - with an open , double-axle trailer and a total weight of 3000, the sway control is a nice plus, but not a hard requirement.

Also your 1993 5.7 engine is rated at 210-215 horsepower. You will likely find you have plently of brakes/chassis/control and are limited more by the HP than anything else.
