Ground Clearance??

Is that a regular 2 wheel dolly like you would move a fridge with?

I have the same jack as ToddsPod (same jack stands too).  I've removed the factory jack, especially before I got risers and a weight distribution hitch that thing hit the ground every time I sneezed.  A real pucker factor when you are doing 60!

Ground clearance also depends on how low to the ground your hitch is.  I've seen some really low hitches on some vans and SUVs where the tong jack scrapped the ground over every bump.  I haven't seen a problem with my Trailblazer.  Honestly, my gravel driveway isn't at all level and has some nice dips and bumps in it and I've never scraped either the tong jack or the stabilizers.  Some of you guys must be really low to the ground.  My honest, but newbie advice would be to drive around with it for a while and see if the risers become necessary.  This is not to say you shouldn't get the riser, for multiple other reasons, but I don't see it in my foreseeable future.  I'm sure that I may scrape the tongue jack or stabilizers at some point while roughing it in some campgrounds, but as long as it's grass and dirt, I'm not too worried about it.     

Love our axel risers!

Thanks again for all of the info. Our inaugural outing went off without a hitch (ha!). All paved roads and a paved campsite. I was amazed at how well the unit towed! Even without the risers or the WDH, it followed behind perfectly; albeit we were on winding mountain roads so we were traveling pretty slow. After years of pop up camping just the fact that we had hot water and a toilet made for a wonderful trip!
