A few tips, from an 04 Allure High Cade, 40' Tag with the same ISL.
- Have you ride height adjusted, and have the set everything to the highest setting possible. Some have even moved up 1/2 -3/4" above the normal top setting. (When I say top, I mean having the rig as high off the ground as possible.)
- My coach had a oil pan protecter installed when I bought it. Don't know if this was a 2004 mod, or something the first owner had done. But it's been enough to protect from both minor scraping of bumps, and tossed up road debris. Might want to cal Kevin Waite, or also Oregon Motor Works, to see if they know if this was a kit that was available. And if you can get one. If not, it looks like heavy metal fabrication, and a bit of welding, to accomplish making one. (I attached a picture, but dang if I t did not come right in at the edge of the pan. Look carefully, and you'll see the edge about 1 -2" below the pan.)
-When driving, especially going into and out of driveways, campgrounds, or just uneven roads and trails. Remember you can always raise the coach via the leveling system. Front, rear of both. This gives you quite a bit more ground clearance.
Between 5-6 years for us with this coach, and have only dragged the ground on a dirt berm one time. This was with the tail raised as high as it could go. And, it was that or back up down a tight twisty dirt road about 3/4 of a mile. The work camper at a campground, was leading me, said he showed many people this 'short cut', that cut off about 40 mins of driving... No damage as dragged the skid protector over this mound of dirt.
(And caution, I have Road King shocks all around, and they're robust enough to handle raising up the coach high. Not sure if it is the same with your coach, but some 2003-2004 (maybe others) Country Coaches, could raise the rear end up high enough to snap one of the rear shocks. Drive axle, not tag. Limiter straps are available to prevent this over extension.)
Engine sitting a bit lower to the ground, does help in stability and handling. But admit that just 1 -2" would have probably made this a non problem
Enjoy your coach, be safe,
