I’ve added an iPhone mount to the side of the LT1 using part of an old cheap plastic camera tripod. It’s screws into the 1/4 inch mounting thread on the side. It folds flat when not in use.
This will work very well in our RV. There is a small 12“ x 12“ side table by the queen size bed. This will easily hold my LT1 and raise up and tilt my iPhone. It will also hold my earphones and USB power cord.
It seems sturdy with or without the 5 inch rubber base attachment.
