Do you ever wish you had additional storage or an easier way to secure your cargo?
We always are so we up fitted our new shop truck we a RetraxPro EZ-Off FRC-4000 retractable locking bedcover. The beauty of this bed cover is if you ever need use of the full bed you just open it fully and 2 people can lift it straight out in less than a minute, reinstall is just as fast. It can also support 500lbs and is lockable in move positions than any other bedcover.
Next we added the Integral rail system, a modular truck storage and organizational with Milwaukee pack out organizers. It adds additional cleats, ratcheting tie downs built in, and the Milwaukee storage containers.
No longer do we have to search for tie downs or places to hook one too.
Makes securing gas cans, coolers, tools and equipment a breeze.

PSA.......As of June 1st there will be a slight labor rate increase of $5.00 per labor hour. After crunching the numbers we tried to keep it as minimal as possible.

Parts prices have been increasing and we are seeing a lot of fuel and shipping surcharges lately on our orders due to the increase in fuel prices. We are trying to keep them as minimal as possible.

And lastly also on June 1st our menu pricing for scheduled maintenance services will be increasing due to the increase parts and materials.
Labor on the menu services will Not be going up.

Anyone who has work scheduled/appointment for after June 1 will still be billed at the current labor rate.
