What type/size of MH? Chances are are that it is a wheel seal, unless it has hydraulic brakes then it could be brake fluid. Either way it should be addressed before too much driving.
If it is brake fluid, then you could loose your barkes.
If it is an oil seal, then it could also effect your braking system by getting oil on the brake pads/shoes.
Are you someplace that this can be addressed there/
