only if its bucketing it down or like some fisherman I know , they can't be asked to set up a full caravan awning, too many poles and ropes etc.
JRC have acouple of poles to slot together, then the rest is pram hood design , sling teh cover over peg down finished.
More time for fishing and all your gear don,t get wet, and neither do we.
Just bought the JRC brolley for short day ticket trips, can,t wait to try try it.
