Our Wilderness, like other lightweight TT in the Heartland lineup use the Wide Trac axles, which make for great towing. The downside is when looking at products like Bal X-chock and others between the tire devices, they become costly. I have seen those made from 4x4 blocks, and they work, but can take up valuable space. Below is a set I made from 1 inch square tubing. They are lightweight, easy to install, and require little room. Most importantly, they work! I no longer feel like I am going to fall out of the shower because the wife rolled over in bed.
