Hi folks: I took the plunge yesterday and ordered the ARE CX HD; it will have the solid drivers side swing-up panel, a swing-up passenger side window with middle slider, a front fixed with middle slider (drop down not an option with HD frame) and the HD roof rack that is integral with the frame. It will also have a carpet liner.
The four risers to the roof rack bars connect directly to the HD aluminium frame through the top of the cap so the cap itself bears no load; good for 550lb on the move. It will take 4 to 5 weeks delivery; I'll post detailed pics once it's up top. It was not cheap; about CAN$3400 installed including taxes. I went with the solid drivers door because that's where my tools, compressor and other goodies are going to go; I'll build my own divider/tool storage arrangement.
Despite the multitude of picture of bigger roof top tents on a host of vehicles with a host of caps on the Internet, the feedback from cap suppliers was too vague for me to feel comfortable going without a higher, guaranteed load rating. I also spoke to several overland stores that specialize in RTTs; they too stated that fitting RTTs to SUVs, Landrovers, whatever with full factory roofs is never an issue but putting them on fibreglass canopies can be a compromise. One guy I talked to reminded me that a 200lb on-the-go rating for a cap can be pretty much divided by two when off road due to the extra bumps and that he had seen lots of cracked gel-coat on customers' truck caps.
