I am the old guy in the video, if anyone has any questions about my experience, feel free to pm me. I don't scan rv.net regularly so sorry for not catching this sooner.
I will say as I did in the video, that Rico Titan was awesome to work with to find a solution for the difficulty in getting the front castors to swivel, without any additional cost on my part. I did a video of the difficulty that I posted on YouTube but replaced it with the one showing what they did to correct the problem. If there is a way to email it, I'd be glad to share it. Lots of nice creative ways to solve this as shown in this topic, but I don't have a welder nor would I trust anything I came up with to support the heavy TC. Not to mention I probably would have not guessed to try an offset pair.
