Frequently asked questions about Happijac Camper Jacks

Here are the answers to questions we here the most. If you do not find the answers you are looking for, please click here to electronically ask your question to a Happijac representative on line.

What is the price of the Camper Jacks and what is the shipping cost?

done through UPS unless requested otherwise. To find shipping cost, contact Happijac and give
them your zip or postal code.

What models of camper jacks does Happijac make?
Happijac makes a 4150 series acme jack, a 4500 series ball-screw jack,
a 4600 series ball-screw with quick-release-leg, and a 5000 series hydraulic jack. See product overview under the jacks link on the left for more information

Will Happijac jacks fit on my existing mounting brackets?
As long as your existing mounting brackets are Happijac brackets they will fit any of our jacks.
Each Happijac camper jack uses the same universal Z-bracket mounting system. Providing
superior strength and security, the Z-bracket mounting system is easily installed and/or
retrofitted onto most any camper. Once installed, you never have to change brackets again,
regardless of the type of Happijac camper jack you place on your camper.

Do you have a swing out bracket for my dually truck?
Yes. For dual-wheel pickup trucks, the optional swing out bracket is easily installed and
provides the additional clearance needed for trouble free loading and unloading.

Are Happijac manual crank jacks up gradable to electric jacks?
Yes. Perhaps the best feature of the Happijac family of camper jacks is the ability to gain the
ease and comfort of electric jacks at any time without the hassle and expense of "opting
up." The acme (4150), ball-screw (4500), and ball-screw with quick-release-leg jacks (4600) can easily be upgraded into a remote controlled electric jack system with the purchase and simple installation of the Happijac motor (600500) and wiring kit (600530).
