Winterizing - headache or breeze?

I have a Sundance 2998RB that has been a great unit. The biggest problem is winterizing the unit. I have to crawl into the basement storage area, remove a panel and stretch and squirm and wiggle to get my hand in far enough to reach the hot water heater bypass. Also the valves to draw anti-freeze in are in this compartment. How is this accomplished on a Gateway unit? Pictures would really be appreciated. I'm hoping to upgrade this summer, but Heartland's website has been down for 2 days now.

Thanks for any insight.
