Hey Pablo,
The Replacement Lippert Correct Track Weld-On Axle Hanger # LC303918 only comes with slots because it's designed to work with the Correct Track system. What you have is likely OEM only so an exact match would need to be purchased directly from the trailer manufacturer if you wanted to have both the slot and single hole. view full answer...
Thanks for reaching out!
I recommend going with the Advent Air Low Profile RV Air Conditioner which comes in White # ASA86YR as well as Black # ASA68YR. These are rated for 15,000 Btu and come with the start capacitor so they won't draw as much power for the startup as a normal unit will.
I really like the low profile design because it looks more sleek and gives your RV a lower profile without sacrificing the performance of the AC unit. view full answer...
