The all-new, American-made Towtector could be the answer.
The double-brush system hangs from two solid bars attached to a bracket that slips over a Hayman Reese tongue. The brush allows air past the diff, which helps cooling. The patented bar across the brush holds it in place, preventing it from lifting while travelling.
The Towtector comes in three widths: 96in (244cm) for big motorhomes, 78in (198cm) for F250s and the like, and 70in (178cm) for 4X4s and utes, priced at $495 for the 96in and $450 for the other two sizes.
