Our 1st TT didn't have the gas assist door holder. Our 2nd one did and for us anyway it was great. At 1st I thought it would be a hassle. But it's really nice to have the door open on it's own. Just pull the door handle to open, let go and the door opens automatically. Ours had the same type gas struck found everywhere from canopy doors to your lift up beds. We used it for 2 yrs and not a problem. We just purchased a new 5th wheel and it is the old style that you have to latch to the side of the unit. FWIW our hot water heater was behind the door so I'm pretty sure that's the reason for the door only opening 90 deg.
