Yes it does
We own one and it does go down.
You can sleep at least 10 people in the unit. 4 bunks -2 couch-2 dinette-
2 front bed.
I have a 2000 silverado ext cab with a 4.8 liter, 3.73 gears, tow/haul mode and I am maxed with weight for truck. But it pulls it okay.
Should have a 10,000 lb wdh setup and diffinatly need a sway control.
We like the unit very much and spent 35 days total in it. pulls okay
Check with chevy and find out what your gross combined gvwr is
Mine is 12,000. I'm at 12,600 lbs loaded to camp.
Can e-mail gmc canada and give them you vin for truck and they will let you know what the CGVWR (exacte weight) of unit is.
the 31qbs dry weight is around 5,900 lbs with propane tanks full and battery.
you will be surprised how much extra weight you pack with all the extra kids stuff in to trailer.
Man I did and I don't have that many Grandkids
I would want a 5.7 or higher to any major pulling or long hauls.
I will be upgrading to a 3/4 ton in about 4 years, before I hit the road full time
