We have a few vintage travel trailers, and as is true with many classics, their parts and systems wear out and can be hard to repair or... read more replace. On several occasions, HEI has been more than helpful in keeping these beauties on the road. They recently located an uncommon 12 volt battery and later were able to modify an obsolete fuse that will now accept modern ordinary components.

Excellent customer service.

I needed it immediately to head out on a hunting trip the next evening so I had it shipped UPS Next Day.
