First...I did search this, and didn't find what I need...

I'm looking into buying a '94 Rodeo 4x4, but part of its use would be behind our RV. I know they sell the brackets for flat towing it, but it looks like they only want to tow at 30mph! I saw something mentioned about adding a neutral position to the transfer case...is that for real? If so, what does it take to get it done? I know another option would be to throw in a Waggy D44 and install a full floater kit. I don't really want to go that deep though. The last option is to disco the driveshaft...but with my parents using the RV and Rodeo, its not an option for me.
Does anyone tow their Rodeo as is (stock)? Any tips would be great!
Thanks!
