Helpful Tip: Decks
At just about every seasonal campsite, the resident has added a deck. The problem
with a permanent deck is you will have to tear it apart if you would like to reposition
your RV. A solution to this is to build a modular deck system consisting of multiple
4’ x 8’ sections bolted together. Then when you want to move it you can unbolt it
and if needed move it in sections in the back of a truck. This method does require
more pieces of wood but the structural members are much smaller. Additionally, each
corner must be supported by a footing. If built according to the method described
below, the decks should meet local building codes. However, you are responsible
for verifying the design meets local codes.
Lay out two 2x6-8’ rim joists on saw horses and mark intersecting joists locations
16” on center. Using a scrap piece of 2x4 as a guide, install joist hangers so the
2x4 guide is flush with the top of the rim joists. Starting with one of the long
rim joists using 3” screws, install the end rim joists. Then install the middle
2x4 joists into the joist hangers. Follow up with the other long rim joist and repeat.
Now you have the frame built.
Place the frame on flat ground and install the two straightest lengths of decking
you have along the long rim joist flush to edges. Using 2” screws, attach one screw
to each joist. Square up the mini deck by measuring from corner to opposite corner.
The measurements need to be the same or the additional decks will not be able to
be bolted together. If not, push or pull on the corners till they are. Finish screwing
down the deck boards you have already attached. Place remaining deck boards between
the two you have installed, spacing them equally.
Drill bolt holes for the carriage bolts in each joist bay and 3 on the ends. If
you space them the same way on all modular units, then the deck will bolt together
no matter how you arrange the units. Mark out on the ground where you plan to place
the deck. On each of the corners of each of the modules, you will need support.
If on grade level you may use patio blocks to support the deck. Pier blocks can
be used if you need a little more height. If installing the deck higher than that
you will need a regular deck footing.
If you are not able to crawl underneath to bolt it together, a deck board (one at
a time) may be removed and reinstalled after the deck is in place. If you doubt
your carpentry skills, please contact a local carpenter for help.
