So we’reready to build a new travel rig but I’m stuck trying to decide between an extended SMB sprinter w/ 4x4 or a Bengal Tiger. We travel long distances across the US vandalism Canada visiting national parks. 4wd is a must dues to mud and snow but I don’t do hard core off road. I want the pass through convenience for safety and ability to access the rear while traveling. Due to winter travel, an indoor shower along with cassette toilet would be a must. I’m looking for suggestions or pros and cons that I might have missed.
