I have a 2015 24.1 Vegas with HWH hydraulic jacks. They work great, but are a bit low for uneven campsites... sometimes one of the fold-down jacks will hit the ground before extending. I'm scheduled next week to have that problem addressed at the dealer.
I've also installed a KVH Trackvision A9 satellite dish. Pretty cool at only 5" high. The in-motion feature isn't much good without an inverter, but so far it works very well in camp.
I added a Safe-T-Plus steering stabilizer, rear track bar, and beefy rear swaybar that dramatically improved handling. Small tweaks left to do and I'll be a happy camper.
