Unless you stay at campgrounds that are way more level than the ones I stay at I am sure you will want a levelling system. Plus if the trailer chassis you use is air-ride (the only way I would go, springs would just destroy everything) you will have motion transfer.
This is what is on my Haulmark class 8 motorhome conversion..they offer up to 40,000lb/jack.

I have never used this system but it is an option...12,000lb/jack

Make sure and do the actual weight calculations for what jacks to use, on my coach they put 2- 8000lb jacks just behind the cab (approx 6ft behind the steer axle), coach is 15,400lb on the steer axle and 16,000lb of jack 6 ft back won't lift the tires off of the ground. It struggles just to get it level on flat ground.
