If you absolutely have to flat tow it do it well and be smart. I would highly advise that you rent, borrow, beg, or steal a trailer though.
I flat towed my K5 blazer fully decked out with top, doors, cage, 37's, 3/4 ton axles, with 800lbs of stuff inside it 1000 miles from AZ to CO. I built a towbar out of 1.5"x.250 wall square tube and used a 2" trailer hitch. I attached it to my HD bumper I had built. It attached to the D-ring mounts for recovery shackles with 1" bolts that I drilled for cotter pins so the nuts could not come off. I also used a set of brake lights on the back so people had some idea I was stopping. This trip was made with a 2005 F250 as the tow vehicle and it did pretty well except if you had to panic stop. I almost at **** in some traffic in Colo Springs, CO.
I towed like this 2 other times behind my 98 Dodge Cummins extended cab longbed. All was fine behind this truck except when i was trying to stop kinda fast on wet pavement, and I slid right through a light that had just went from yellow to red. This trip the K5 was unloaded with no doors, top, etc. (wheeling trim).
Can it be done, yes. Is it the best idea, NO!
If you are planning on towing this behind a 1/2 ton you are in for even more fun as your brakes won't be as good as either of the trucks I towed with and your load will be heavier.
Also note that technically in many states it is illegal to flat tow anything over 3500lbs without having functional brakes on the towed trailer/vehicle.
One last note for you if you decide to build a towbar and do this. Put the bar at a slight downward angle to the vehicle that will be towing it. That way during braking and cornering the bar will apply downward pressure and transfer some weight to the rear axle of the towrig especially if your towrig is a pickup truck. If you are towing with a pickup put some weight in the bed.
A friend of mine flat towed his K5 behind a single cab 84 K20. The first attempt at flat towing almost jack knifed his truck in the first corner because the towbar angle was flat and the bed of his truck was empty. After putting a downward angle on the towbar and adding weight to the ass end of his truck he was able to make it work ok but he soon bought a trailer since on the return trip from wheeling his K5 he had to make a panic stop and couldn't so he ended up in the dirt on the side of a major highway trying to avoid hitting the person in front of him and also trying to avoid jackknifing his truck in the dirt while trying to slow his truck down. His K5 weight about 5500lbs.
