First post, gleaned some good information off site time to share. 2007 pc 2350. Launching a boat on steep slick boat ramp was an issue. Sliding backwards with the front tires locked up was a rodeo. Rear tires would not lock up. Searched internet some tips, air bags to lift rear, put transmission in neutral, tire chains even, etc.. helped little. Then I tried applying a little emergency brake. Enough emergency brake to stop front tires from locking up but let motor home roll backwards in neutral. Problem solved! Also installed rear camera on all the time. Hope this helps someone.
