Trailer Hitch Option for 1991 GMC P30
For an RV application the # 41990-16 is an option as this is a great multi-fit hitch typically used for service body trucks. Since we know that the P30 chassis has 34 inches between the frame rails this hitch should fit just fine since it has 16 inch drop brackets that can weld anywhere on the 44 inch wide crossbeam of the hitch. If you needed a hitch with less drop in the mounting brackets the part # 41990-07 has a bracket height of 7 inches instead.

The main difference between the Draw-Tite Hitch # 75121 and the Draw-Tite Hitch # 41121 is the towing capacities of each hitch when a weight distribution system is being used. The # 75121 has capacities of 7,500 lbs GTW and 750 lbs TW when used with weight distribution, whereas the # 41121 can handle 10,000 lbs GTW and 1,000 TW when used with a weight distribution system.

Recommended Trailer Hitch, Brake Controller and Wiring for 1993 GMC Rally 3500 Van
For your 1993 GMC van I recommend the Draw Tite Hitch part # 41121, which you referenced. If you have the step van, you will want a multi-fit hitch as there are no custom fit hitches confirmed to fit your vehicle. I recommend the Curt Hitch part # 13703. This hitch can fit vehicle frames that are between 22 and 72 inches. As long as the width of your frame fits within that range this hitch would work well for you. For trailer wiring you would want the part # ETBC6. The brake controller...

Trailer Hitch Receiver for 1981 Brougham RV on a GMC Van Frame
Since your GMC vehicle was given the RV modification treatment and now has additional components not found on the standard version I think your safest bet is to use an adjustable RV hitch that gives you some installation flexibility. Odds of an interference issue are greater with a custom-fit hitch. Our range of frame-mount RV hitches appears on the linked page and these products include both weld-on and bolt-on hitches with various weight capacities. These are made to fit a range of frame...

Brake Controller and 7-Way Recommendation for 1965 GMC Van
You will need to start with a 4-way (if you do not have one) on your 1965 GMC Van. For that you would want the # 119250KIT. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This...

Installing Trailer Hitch on 1995 GMC Conversion Van with Aftermarket Bumper
The custom trailer hitches we have available for your 1995 GMC G20 Van, such as the Curt Class III # C13016 that you were looking at, do indeed feature pre-drilled holes that are designed to line up to existing holes in the van's frame rails and bumper. If your van doesn't have the existing bumper bolts and nuts that are used to secure the front of the hitch you will need to drill into it (and obtain the necessary hardware) to make this connection. I really can't recommend passing this...

Comparing the Curt Reflex and Curt TriFlex Trailer Brake Controllers
The main difference between the Curt Reflex Trailer Brake Controller part 51130 and the Curt TriFlex Trailer Brake Controller part # C24VV is that the TriFlex has a triple-axis accelerometer with nine boost settings and the Reflex has a dual-axis accelerometer with four boost settings. The triple-axis accelerometer is going to provide more uniform braking than the dual-axis accelerometer and the extra boost settings are going to allow you to really fine tune the braking power output to...

Can Curt Class III Trailer Hitch # C13016 Be Used with Weight Distribution System
The Curt Class III Receiver Hitch # C13016 referenced in your question is indeed rated for use with a weight distribution system. When a weight distribution system like the Reese Steadi-Flex # RP66560 you referenced is used with the hitch its towing capacity increases to 10,000 pounds and its tongue weight limit increases to 1,000 pounds (compared to 6,000 and 600 respectively without a WD system).

Hitch Recommendation for a 1993 GMC P30 Step Van
For your 1993 GMC P30 step van you are going to want a multi-fit hitch as there are no custom fit hitches confirmed to fit your vehicle. I would recommend the Curt Hitch part # 13703. This hitch can fit vehicle frames that are between 22 and 72 inches. As long as the width of your frame fits within that range this hitch would work well for you. For ball mounts I recommend the etrailer Ball Mount Kit # 989900. It comes with 2 ball mounts, 2 balls, a hitch pin with clip, and a carrying bag.
