The easiest way to reduce the weight of your truck camper is to remove any unused equipment. If you’re not using equipment or items on your camper, remove them.
Consider using aluminum if you plan to renovate or modify your truck camper. Aluminum is substantially lighter than other metals and can do the job in many instances.
However, while aluminum will do the job in many instances, it’s not perfect.
If you need it to carry the weight of a hefty load, it may be better to use a sturdier and more capable piece of metal.
