I just completed the installation of JT Strongarms to firm up my 42' fiver. Start to finish was about 2 hours. I began the process by thoroughly reading, reviewing, high-lighting, and underlining the instructions from the kit. As I've seen other reviews describe, the instructions are very poorly written. Very poorly. But - alas! - the instructions read several times that if you have any questions, simply give them a call. I assembled several explicit questions and gave them a call before I began.
I described my questions to the technical support at LCI, identifying inconsistencies and inaccuracies in their instructions, seeking clarifications. To my surprise, the gentleman on the phone became short, providing snarky responses such as "now I'm going to use a big word like triangulation..." disregarding my questions, and simply concluding that if I deviated at all from their (poorly) written instructions, it would void all warranty. Was I speaking to their technical support or their legal department? I concluded the conversation with none of my questions answered, and that I can read between the lines and I'll just figure it out. Which I did. In only 2 hours.
I guess my point is this: their instructions are not explicit and have conflicting information, their technical support was not very technical nor supportive, and with some analysis and preparation, one can figure out the system to have an effective product installed upon completion. We're not splitting an atom here, just trying to get rid of unnecessary movement in the trailer.
I'll be sure to follow up in this post with pictures and maybe some tips, as my previous searches did not yield many results for the questions I had. If I can be of more help to a fellow RVers than LCI, I'd be more than happy to assist.
