We received ours this past Monday. Currently installing lights for our fire department. I am very impressed with the unit! I am hoping to get one for my shop truck next year!

When I drove this truck through multiple campgrounds in the Rocky Mountains the Rangers mentioned that they weren’t accustomed to campers bringing their own bear boxes lol. We were in heavy Grizzly country. The boxes kept a lot of expensive gear dry and secure even when I power-washed the truck.

I have been meaning to sit down and write this sooner but better late than never. We are extremely please with our Iconic-X Drop in cap. It has been worth the wait. If you remember I am the Chief of a small combination department and I respond to all types of calls. Your cap quality and functionality are outstanding. I have attached a couple of pictures of our finished truck for you.
You should also know that there are several departments and agencies in this area that are looking at our truck and your cap.

After working out of the pack for the last 9 months, I have to say it is a great setup. Perfect for me as an electrical contractor. You cannot appreciate the level of quality until you see these in person. The welds and overall quality are second to none. I’ve had at least 12 service trucks over the years and I am the most pleased with y Iconic-X pack. Check em’ out!

We’ve had the box on the truck for a while and have absolutely loved it. Now, it is full of equipment and we have finished labeling the truck as well. We’ve taken it on a few jobs and it’s the perfect light rescue unit for us. We get tons of questions wherever we take it because people seem to love the box! Thanks again for such a high quality product.

Just wanted to express my appreciation. Got the box Thursday last week 10/21. Got it installed last weekend. I love it and it is great! The quality and workmanship far exceed my already high expectations. Love the product and it was well worth the wait! Thank you! Please pass along my appreciation to those in design/development and manufacturing. I have added some additional lights inside and out. I still have some organizing to do, but the pics are from the afternoon of install prior to additional lighting install.

I got mine a few months ago. They are quite expensive and the wait time was long……but they are amazing. They keep everything dry and they keep my work truck a lot more organized than before… I would recommend for sure.

“We love the pack! The setup has turned out amazing. The guys love it and the departments around us have been full of questions about it. We are very pleased.”

I finally got the lettering done this week and took some photos. You can see how I mounted the radio heads in the back they are also in the cab up front so when we go into command post mode we have the rear radios. More lights and scene lights coming soon.
The pack is amazing and does everything we need. Carrying Hazmat/Decon, Bleeding Control/MCI, radiation detection equipment and radio comms. Police, fire and EMS crews compliment the pack and getting a lot of questions so forwarding your info to those who ask.

Extremely happy with my purchase. I meant to email you back last week. I received the box December 8. Installed it as soon as it came in. It fit perfectly. Looks like it is built very well.

I love the box. We shopped around and realized nothing compared and now that I have one I could never go another route. Every place I take this truck I end up with all these tradesmen asking me questions and what not. I’m hoping by the end of this year we will be putting another truck together and be ordering another insert.
