What kind of hitch to use is like asking what kind of oil to use; a conversation that could go on for hours and never come to a common agreement.
You need to ask yourself how often you are going to take the hitch out. Will it be too heavy for you to handle. Are you contemplating a long bed truck or short bed.
I have a Reese 20K. It breaks down into two pieces so it is much easier to remove. But then I don't take the hitch out unless I need to. I wanted the Reese signature series but it would not fit my truck (I have a package that comes with Rancho shocks and they relocated one of the shocks. Reese did not have a compatible mounting system - at least not at that time). However, the mounting rails on the bed does not concern me. With the hitch out, they do not get in my way at all.
Now, are you thinking about a SB or LB truck. Now you need to be thinking Slider hitch or not. This would be a separate conversation that too could go on for hours without agreement. I personally think you need a slider hitch with a short bed. Now you are going to hear from the faction that can make the tightest turns in the world without a slider hitch. Here is why I don't agree with that. I had a short bed Ford with a slider, but in one case I got complacent and did not slide the hitch when backing up once. It got real tight and I ended up with a dent in the back of the cab and blew out the rear window. I'm sure my Ford SB was the same length as other SB Fords, so I refuse to buy the argument that it will work. I had a Reese slider and it worked great. If I had been educated then (didn't learn about iRV2.com until long after this incident). I learned alot from this site and when I got to the point of replacing that Ford truck I looked into the PullRite hitch. However, the cost difference between a longbed or shortbed truck was a lot less. I've had longbed trucks ever since.
Fianlly, I do not find any inconvenience of driving a longbed dually as a dialy driver.
DRW vs. SRW - whole `nother post for that one.
