roof strength issue
buzz this is in response to your thoughts on standing on roof.i had that problem when i had to get on roof to load kayak,what i use is part of my build on the inside. i have added compartments inside at floor level (you can see some of the frame in pictures on the roof lifting thread)the cover for the storage areas are made out of 1/2"plywood covered with indoor/outdoor carpet ,and fit into frame work which is made out of 3/4"angle they lift out and then i use them carpet side down on roof,no slipping ,no scratch on roof(be careful if you use plane plywood as it will slip!),as i have panels that are used to convert bench height storage into bed to use when top is not raised i can cover a large area 0f roof ,also when i have rack mounted basket mounted it is large enough to set on with two people (we use it to watch races etc) that was another reason i edge mounted roof rack bars.going on 5 years of use with no problems,hope this gives you more ideas .as a side bar a wire welder will pay for itself after the first project or two,very easy to use!!drive slow and enjoy "its the journey"
