Huh. Strangely, just today I did battle with a 22 degree offset sewer connection. But mine points towards the road, not the front of the RV. It overflowed while I was dumping. Sewage. Ick. But, the sand surround sucked it up pretty quickly and once I slowed down the flow (which I've only had to do a few times in 13 years of full timing), I was able to get the tanks emptied.
Than I took a bucket of bleach infused water and dumped it all around the wet spot. Killed the smell immediately.
No fix other than contacting the park groundskeeper for the overflow. As far as connecting? Nothing to it in my case since it's all sand.
Can't you dig a bit out so you can wedge your connector in there?
