Used tow dolly

The hitch seems to be low to the ground. My rig hitch is much higher. Do I use a drop down hitch or should I cut and weld the trailer to match my rig?

Either method has both advantages and disadvantages.

The use of a DROP HITCH receiver adapter seriously and I mean SERIOUSLY downgrades the tow capacity of the hitch, If it's a 5,000 hitch you could well end up with the dolly being all it can tow safely. If it's a 10,000 hitch you might be OK.

However if you do this the Dolly remains "Full strength".

The cutting and welding of the trailer (dolly) also weakens it in many cases... But the hitch remains 100%.

So it amounts to which one do you wish to reduce the capacity of.

A good weld shop can minimize the damage to the trailer.

Use a drop down hitch for the dolly.
It will put very little hitch weight on it to be any problem.

You certainly don't chop up your dolly. You buy the correct hitch parts to match trailer to tow vehicle.

You want as straight a line as possible between tow vehicle and toad. If the dolly is not level, front to rear, then you need to either lower or raise the ball mount (or combo shank and ball mount for fancier ball mounts with a separate shank).

They make ball mounts that will handle your requirements. For example, here is a fixed ball mount for a 2" receiver and with enough weight capacity to tow up to 12,000 pounds:
Link: Ball Mount 7" Rise or 8" Drop, 12,000 lbs Draw-Tite Ball Mounts 4283

8" drop not enough? Here's an adjustable one with over 9.5" drop rated to tow a trailer up to 6,000 pounds:
Ball Mount Adjustable Fits 2" Trailer Hitch Receiver, 6,000 lbs Hidden Hitch Ball Mounts 80412

Here's another adjustable ball mount with towing capacity of 10,000 pounds or 14,000 pounds, depending on the weight capacity of the ball you use, with adjustable rise up to 5.25" and adjustable drop down to 6". That should be enough adjustment to get that dolly level if you don't have your tow vehicle lifted.
Link: Channel Style Adjustable Ballmount - 2" & 2-5/16" Balls - 14,000 lbs Curt Ball Mounts C45900

Look around at the other fixed and adjustable ball mounts on the ETrailer.com website, and you'll probably find one to meet your needs.
Grumpy ole man with over 50 years towing experience. Now my heaviest trailer is a 7,000-pound enclosed cargo trailer, RV is a 5,600 pound Skyline Nomad Joey 196S, and my tow vehicle is a 2012 F-150 EcoBoost SuperCrew.

Check it after you decide which hitch you're using, mainly the ramps because if not correct they could rub and scratch the underneath of the car or if not right they could drag the ground while traveling. Jim

The trailer tongue should be level of course but using large drop down hitches can put a strain on the receiver. I have used drop downs both right side up and upside down to raise or lower the tongue but was careful not to overload the hitch.

Obviously a 3" drop down will have less affect than a 7". Just use common sense and/or ask at a trailer dealer.

Well, of course your receiver must be strong enough to handle the weight-carrying (WC) load of the trailer, including the added leverage of the drop-down ball mount. Most OEM receivers are rated for 5,000 or 6,000 pounds max WC (without a weight-distributing hitch). If you need more weight capacity than that, then they make those too. Several brands are available with WC rating of 10,000 to 14,000 pounds. Here's a Curt receiver rated for 16,000 pounds WC trailer weight. That one is for a specific tow vehicle, but they probably make them for your tow vehicle too.
