One thing to keep in mind is that most TCs don’t do that well off road either. So, depending on what you buy, you may/may not be able to do anything other than simple gravel/dirt roads without damaging the TC or bending the frame of your truck. In that case, a DRW isn’t much of a handicap.
You also have to look at the height as well. Extremely tall vehicles won’t do well on roads with many branches across the road. DRWs can also have a traction issue compared to SRWs since the rear tires don’t exactly follow the front tires. This is an issue in mud/snow.
If the roads you plan to travel are nearby, go drive them and think about what they would be like with the TC you plan to carry onboard.
