dingy towing 4 wheels on ground?

I had one on a 1988 Chevy S-10 Tahoe 4X4. I used it for about 10 years. I hated it! Had endless problems getting the splines to engage after towing so that I could drive the S-10. I spent many hours under that S-10 in the dirt and mud to get it to lock in. I had the installation checked numerous times and nothing improved the process. Maybe it was my vehicle that was the problem; however, IMO I doubt it. I've talked with other Rvers who loved the product. My experience is such that I wouldn't buy another vehicle which couldn't be towed without installing a disconnect drive shaft.
