Ground clearance at rear of a 3124

Does anyone know or know how to find out the "nominal" ground clearance for a 2009 3124KS (I am really interested in bumper clearance)? I want to get a generator and since I am very limited on space, for storage, I want to set the generator down at the very rear of the garage and then back the TM over it (assuming I have enough bumper/bottom panel clearance. This will require that I have 24.3" clearance between the lowest point on the TM and the garage floor.


I know that lifting blocks could possibly be used, but I also want to keep the towing charcterists as close to the nominal design as possible.


Thanks for any input you may have!

Thanks!
