I am trying to find a no drill application to mount my fifth wheel hitch into my 2008 mega cab 4x4. I have found some companies that say you can use a hidden hitch #50040 with the mega cab and other that say you can't #@$%!. Does anybody have a clue?
Look here for the Super 5th Pull-Rite Hitch. . they have a 16K No drill
PullRite has a SAFER, STRONGER, BETTER designed hitch for you
Here is the PDF of the install chart for it. . you will want to get the Super rails (blue chart line). . as you can remove it totally and have a clean bed.

I installed the Super Rail PullRite 5th wheel hitch on my 05 DRW about 14 months ago. It's a little spendy and difficult to install because you have to fish bolts through the back of the box frame to existing holes. I feel it was well worth the price and the hard work. The beauty to this system is that you can remove the two rails and four pins and have a clean bed. If you have an RV dealer do the work, they will probably cheat and drill holes through the frame to install the brackets. At least that's what two RV shops told me. If you decide on the PullRite and you decide to install it yourself, PM me and I can help with a few installation tips.
I also have this set-up and did the install myself. It was very straightforward with no holes to drill in the frame, but I remember drilling the 1. 75" diameter holes in my bed and was all pinched up similar to drilling into my exhaust manifold for the EGT sensor. After the first hole, it was easy...
The only complaint I have is that the actual 5th wheel is very heavy and my bed is too tall for me to remove or install the hitch by myself. I have to get a neighbor to help. Although this is probably true of any 5th wheel hitch.
I have a picture or two in my photo gallery.
I too had difficulties with alignment of the 4, 1 3/4" holes through the bed. I ended up with two slightly egg shaped holes. TDR Member klenger gave me some good installation tips for laying out the 4 holes. Ken's idea is to first place masking tape over the top of the 1 3/4" hole on each of the 4 brackets before installing them. When all 4 brackets are installed, drill a 1/16" pilot hole from the top side of the bed through the masking tape. Remove the brackets and check how far offset the 1/16" holes are to the 1 3/4" hole in the bracket. Adjust the pilot holes to fit dead center over the 1 3/4" holes in the brackets. Finally drill the 1 3/4" holes. With the rails and the 4 pins removed and my heavy rubber mat in place, the clean bed looks great.
As far as removing the heavy receiver hitch, I take the top plate assembly off first then the the bottom part. It's still very heavy, but I can manage it by myself.
I too had this issue; Ken's idea is a very good one. I probably drilled 4ea 1/16" holes for each of the four 1. 75" holes to get it perfectly centered with the bracket below. I used a paper clip that I unbent and shaped into an "L" with a short side and a long side. I would drop the paper clip into the 1/16" hole and then go under the bed to see how far off I was.
Do not just follow the directions and use the tape measure method. Its only accurate to +/- 0. 5"...
It's a tough job. Did you have any problem with fishing the passenger side, set of two bolts, through the box frame under the rod (through the frame) for the exhaust pipe? I did. After installing the front brackets, the rear brackets were a piece of cake.
Since you have a mega cab I assume your getting a sliding hitch, I recommend the superglide. The no drill super-rail kit for the superglide does not require fishing bolts through the frame. and is very easy to install. I was getting worried reading this, I thought I left some bolts out when installing my hitch,, I had to go to pullrites website and verify that the super 5th, and suerglide have 2 different mounting set ups!
