That is a Curt class 3 hitch that utilizes the bumper only for support / capacity. personally I wouldn't trust it past a class 2 and just use the bumper.

Take a look at http://www.etrailer.com/hitch-2007_Dodge_Ram+Pickup.htm and the hidden hitches; particularly part number 82534 for a frame mount hitch which will give you a true class 3 hitch. There are class 4 & 5 on there as well; but installing one of those is overkill for your pickup. You'd be able to exceed the GVWR; which you want to avoid.

If you have any trailer shops nearby, they should be able to hook you up with a the proper hitch as well. Good luck!

I've personally seen the little one get ripped off of vehicles and I've had the frame mounts break off as well (bad bolts to the frame from original installer). When it comes to reliability, I like grade 8 bolts to the frame with locking hardware. The small one goes to the bumper supports and the bumper itself (I don't remember if the bolts remained exposed or not though). Not ideal in my opinion.

The price difference doesn't look to be that great between the two on the etrailer website. I would recommend the frame mount just for the off chance you get stuck off road in the future and that's where the recovery vehicle wants to hook to. Would you really trust that bumper mount to fully support your vehicle without damage? The frame mounts have typical safety factors of 1.5 or greater, so even a class 3 frame unit will support a regular cab pickup that is fully loaded.

The 600/6000 seems overrated to me on the bumper only unit. I can believe it for the frame mount and you would be less likely to rip a properly mounted frame mount off the vehicle if it was stuck once it is properly installed.

You never know if you are going to get stuck and need a pull, nor need to pull someone else out. I've seen too many bent bumpers or bad hitches from improper towing techniques to recommend the bumper only mount.

Ultimately it is your decision, I can only suggest that you think ahead for what could occur and plan accordingly.

Good luck with the purchase and install.
