I recommend seeing Tom service manager at Glenn E Thomas and he can hook you up with an advisor. He's been there for a good thirty years and super good people. Been bring my Vipers to him for years and will bring the JT when need be,
Hope this helps.
Installed a Softopper on the Gladiator today. Had one on my 04 Titan that I installed in 06 and still looked/worked great in 2020 so bought another one. Highly recommend if your looking for a bed shell that’s easily removed or able to lower in minutes.
