London coach Tony Rea was delighted his troops ended their season on a high note following a 48-42 success over Hull KR.
The Broncos led 24-0 and 42-26 in a game that had massive momentum shifts, and were hanging on in the face of a Rovers fightback late on.
The home side looked on cruise control in the first 30 minutes, taking the game by the scruff of the neck thanks to tries from Michael Robertson, Omari Caro, Dixon and Chris Bailey.
But two tries in the final 10 minutes of the half from Micky Paea and Richard Beaumont kept things interesting at the break.
Dixon and Robertson then struck again, but Rovers tries from Dave Petersen, Chris Heil and Con Mika ensured it was game on again.
Olsi Krasniqi seemed to have settled Broncos nerves with a further score, only for Ben Galea and Michael Dobson to reduce it to a one-score contest.
Luke Dorn added the finishing touch for London though, leaving Mika's second try in the dying minutes a mere consolation.
"I am just delighted that we found a way to get a result," commented Rea.
"We had to find a way to get through some very tough periods and emerge emotionally.
"I thought both teams were in a strange position going into the game as there was nothing really riding on it.
"But we had some big performances out there from the likes of Mark Bryant and Kieran Dixon continues to do some wonderful things."
Rovers coach Craig Sandercock said: "Any loss is disappointing and this is no different.
"I thought in the first half it looked as though we were playing a training session.
"It always looked as though it could be a high-scoring game due to the weather but I did not expect that.
"I knew we had some points in us and if we were able to complete our sets we could make it a contest, but we gave ourselves too much to do."
