I have a 2013 28BHBE, it will sit much higher than your popup. I have a gravel driveway, so these measurements are not exact, but should be close-
Bottom of bumper to ground: 22-23 inches
Bottom of rear stabilizer jacks to ground: 16-17 inches
Bottom of sewer outlet to ground (sewer outlet is about halfway between back wheel and bumper): 13-14 inches
Hope this helps!
