Water in underbelly

[Missouri777]

Hose blew from fitting on hot water line in camper. Filling underbelly! What should i do

Shut off the water and water heater.
Can you see and reach where the lines blew apart to repair it yourself? If not, if your unit is under warranty, get the unit to your dealer. Not under warranty and/or can't get it to your dealer, call a mobile RV repair service.
You could punch a hole the the underbelly to drain that.

Welcome to the forum. Sorry it was under less than pleasant circumstances.

Only thing I would add to OldmanAZ would be to cut the hole at the lowest possible place near the leak. Otherwise you may drain some of the water but leave more of it sloshing around. Before you move, check to see that all the water is gone. Water hitting the sub floor while moving is not good.
