what is the spacing of the mounting brackets, how can I be sure I will land right on the roof truss?

the screw holes line up at exactly 48 inches so once you line up the first side the other one will fall right into the corresponding truss. they are usually 12 or 48 inches apart.

The mounting brackets are predecessor to match the bolts locations that hold the roof uprights. Just unbolt them and place the bracket and reinstall the bolts. Do one side at a time. It took me about Ten minutes to install both brackets.

it depends on the pitch of the roof. though you should be able to place the hook on the side of the vent if it does not clear. the hook itself has approx a 5" raduis, so that give you about ten inches of clearance.

This roof basket should fit. The manual indicates that the minimum distance between the cross bars should be 25 1/8", max distance is 32 3/10". It also mentions that the crossbars shouldn't be more than 1 1/4" tall and no wider than 3 1/4" front to back. I found all of this information here http://www.cargogear.com/imagelibrary/pdf/uVentureInstructions.pdf

It is measured in inches, beware there is no mounting hardware to attach to the roof rails, I drilled holes and attached using U bolts.

Carefully read the installation steps, they provide info on how to make the bag secure even on roof racks with cross-brace spacing less tan 41" by using the handles. Be sure to replace the provided straps with straps that'll tighten down and remain tight; toss the provided straps, they're not useful. See, http://www.nrs.com/product/1445/nrs-15-hd-tie-down-straps or http://www.nrs.com/product/1446/nrs-15-padded-straps, 1' or 2' straps should work fine.

The rails are about 3.5" off the roof at the brackets. They do create some wind noise, probably depending on the shape of the roof.

Two small keyhole brackets widely space on the back. The website has some pictures. I placed tophats mounts on mine and put them on tripod stands for easier side placement.

should be sufficient. But I like to be on safe side, so used 2 additional straps, running North/South in addition to East/West. This, of course, was using a roof rack.

Hi Billy, you will need to take the factory crossbar weight limit and size into account here. the Hullaport requires at least 17 inches of space on the bar and you will need an additional few inches for the straps and to maneuver them around the boats. It may be beneficial to look at a Thule roof rack system in this case. Please check out the "Buyer's Guide" on www.thule.com.Thanks!

I think it's up to you. Nothing in the instructions. I put it high enough that it's a reach for me, but left plenty of clearance for my head at the top. That came out to 8" from the top edge of the brackets to the ceiling. That leaves over a foot of head room when I do pull ups.

The "U" shaped brackets were smaller than what I was trying to do... I wanted to mount it on my mountain bike. The "hose clamp" style worked great, and has a pretty long size range. Sorry I don't have an actual measurement.

I am unable to climb up on a ladder and measure the brackets. I can tell you that the holes for mounting are right in line on the center of the brackets. There should be no problem concerning the width of the beams.We used some small bunji cords to hold the cords in place between the bike and the brackets. You might not need this on a standard bike, but we have a tandem bike. hope this helps.

I drilled new mounting holes in my hitch to fit the spacing on my tractor. You could do the same if necessary.

The rack has four attachment points on on each side of the ladder. As the rack can be attached between the second from the top step and the top step on the ladder, it can be mounted quite high on a camper. To check if it will fit your application, measure from underneath the second to top step to the highest point on your bikes on the hitch rack below. Then on the bike your are going to hang from the ladder rack, measure from the seat support post to the leading edge of the front tire. If it is less then the previous measurement... it will fit. Also the front to back spacing on the ladder rack is about 6 inches, so there is some room for adjustment if the measurement is close.

Use the rubber expansion bolts for house roof mount. Realistically, however, house should be rail mounted.

Two small brackets fit over a 2" pipe, which I welded a piece of 2" angle to each end of the pipe so the hoist wont slip off the ends. Then I cut 2 holes in the angle and bolted it to my rafters in shed, with another 2" angle on the other side of my rafter for support. Works great, I haven't shot an 800 pound deer yet.
