Practical size/weight limit on toad?

I often see DPs pulling full size pickups.

We have an '04 Itasca Horizon 36GD with the C-7 330HP CAT and the Allison MH3000 trans. We tow an '11 GMC Sierra 1500 4x4 Extended Cab that carries a 2008 Honda GL 1800 on a Rampage motorcycle lift/carrier. We've been doing it for a few years now and, we've not had one issue.

"I just finished watching a youtube video on the dynamax super c rigs. With a 20k tow hitch/capacity is there any reason you couldn't use a full size 4x4 truck as a toad? The dodge power wagon has front and rear lockers, any reason you couldn't tow it?"

The very first thing you need to do is, investigate the owners manual for that particular truck. Specifically look up the part that talks about "Recreational towing-behind a motor home". You may or may not have to bounce around that manual and consult different sections, based on the fact that it is a 4x4 and, has it's "Lockers". And speaking of those, since I'm not familiar with those supplied by them, like I am with factory lockers for Jeep Rubicons, are they "controllable" or, should I say, can you manually engage and disengage them at your control?

I'm going to assume you can due to the intricate/mechanical/logical/safe operations of driving it on the street.

So, if that's the case, then "lockers" on your Dodge truck, have no effect on street manors, unless they're not "selectable" (meaning you can control them). And even the ones that are locked all the time, as in Detroit or Lockright, you can still tow a vehicle that's equipped with those due to the fact that they don't have any effect on road manors while being towed. Anyway, hope some of this helps with your quest.
