Though storing an RV indoors may not be a practical solution, the consequences of leaving your trailer or motor home to brave the outdoor elements can be serious. The sun's harsh rays, along with rain and hail, take their toll on the integrity of the roof and the quality of the paint. Designing a portable, custom PVC shelter is an attractive, inexpensive way to protect your vehicle from harmful weather damage. Having a variety of colors and waterproof materials to choose from allows you to easily coordinate the shelter with your house or other outdoor structures as well.
Construct two right-facing and two left-facing PVC connectors by joining 45 degree connectors with 1.75-inch lengths of PVC pipe. Attach each of these to tee connectors. Turn two of the 45 degree connectors to the left and two of them to the right while facing the opening in the tee connector and glue in place.
Construct one right-facing and one left-facing cross connector by joining 45 degree connectors with 1.75-inch lengths of PVC pipe. Attach each of these to x-cross 1-inch PVC fittings. Turn one of the 45 degree connectors facing forward and the other facing backward from the flat face of the x-cross connector and glue in place.
Measure the distance from the ground to the top of the RV. Cut six lengths of PVC pipe accordingly for the support legs of the structure. Attach left-facing and right-facing connectors to four of the PVC pipe ends and glue in place.
Attach cross connectors to the ends of two of the PVC lengths and glue them in place. Measure the length and width of the RV and add 4 feet to each dimension. Measure the distance from the center of one of the left- or right-facing connectors to the roof peak.
Cut six lengths of PVC pipe, based on the roof peak measurement in step 2. Lay two of the PVC support legs with the left and right-facing connectors on the ground with the 45 degree connections pointing upwards and facing each other. Place these the same distance apart as the width measurement from step 2.
Place one of the cut PVC sections from step 3 in each of the 45 degree connectors facing upward. Glue each of these in place using PVC glue. Push a 3-way L connector onto the top of the two PVC sections to form a peak.
Glue the 3-way L connector in place making sure the remaining roof line connector of the junction is facing the ground. Repeat this process for one more set of support legs and left and right-facing connectors using two more of the PVC sections cut in step 3. Lay the remaining two support legs on the ground with the x-cross connectors previously attached.
Place the legs the same distance apart as the width measurement from step 2. Face the 45 degree connectors upward and toward each other. Glue the previously cut PVC lengths from step 3 into the 45 degree connectors to form a peak at the top.
Push the 4-way LT connector onto the two PVC lengths at the top and glue it in place. Calculate the lengthwise dimension from step 2 and divide it by 2. Cut six lengths of PVC pipe accordingly.
Stand the peaked support leg structures with the left- and right-facing connectors and x-cross connectors upright and facing each. Connect and glue these together at the top and side junctions using three of the PVC lengths cut in step 7. Repeat the process, attaching the remaining leg structure to the other side of the x-cross-connected center-support structure.
Roof Cover Fabrication
Measure the length of the RV shelter and add two inches. Measure the distance from the top of the roof peak of the structure to the bottom edge of the horizontal connecting pipe and add two inches. Cut two pieces of tarp material based on these measurements.
Match the material pieces together so that the sides of the fabric that will show face each other and sew a 1-inch seam down the lengthwise edge. Place the fabric right-side up, and turn under and sew a 1-inch hem along the perimeter edges. Cut nine 2-inch pieces of peel-and-stick Velcro.
Apply the Velcro pieces to the bend of each of the nine 45 degree connections. Cut nine 2-inch pieces of sew-on Velcro. Sew a piece of opposite-sided Velcro to the corresponding seam and edges of the tarp fabric underside and attach the tarp to the PVC frame.
