Re: Roof Rack Advise
I'd say save the weight and the money and skip the full "expo" aluminess rack.
The eyebolt idea is good, but if you want a more permanent rack.
Simple towers and crossbars would do the trick.
If you get new yakima side loader brackets, you can get all the yakima 1A (raingutter) towers and bars you will ever need off of craigslist for cheap.
I have had much better luck over the past 25 years with yakima than thule, but thule makes them as well.
Side loaders mean you only drill in side of PH and not top. Less holes to drill, and accessible (at least on our sprinter PH) to replace brackets when the rust in 5 years of salt water exposure from boards and boats. Plus you can mount them lower to keep the overall height down on the rack.
We have full-length tracks in roof of our penthouse, and I'd save the holes if I could do it again (plus I think SMB west just used wood screws of something equally ghetto to attach tracks)
Added bonus of yakima, is every accessory they make is available on craigslist for a fraction of the cost.
