This is a How-To video for upgrading a trailer tongue box on a 2019 Grand Design Imagine XLS 21BHE travel trailer to hold two UNOWIX Defender X100 Lithium Iron Phosphate batteries that are Group 31 size. Reasons to upgrade to a trailer tongue box would be more storage capacity or upgrading batteries that don’t fit within the existing battery tray. I walk through each step in this video.
