Installed the Sprinter Roof Rack and Deck Panels over the Lemans Roof vent on a 144 Sprinter. This allows enough deck space to put 3x175W walkable solar panels on top of the rack panels. Depending on the needs of each trip we can have a deck to sit on, room to store things, or a lot of solar. Very happy with the installation. Have not yet had a chance to travel with it as van build is nowhere near complete.
Rack and roof panels were very easy to install. Parts were manageable in weight and size and instructions were clear. True one person job.
Installed Lemans fan with a DIY Vans adapter to fit the channels in the roof. There was at least 1/2ā clearance if it needed to be under a cross bar. Mine was just under a panel so had 1 1/2ā clearance.
The 175w solar panels fill out the area on the rack which is great to maximize solar power, however, a good deal of thinking, measuring and precision was needed in mounting.
Very happy with Orionās products, shipping times, and had great responsiveness from customer service as I was planning.
