We purchased a 2018 GD Reflection 303RLS last May and have been camping several times with it. There is no longer problems with wheel bearing grease getting on the brake drums. The oven/stove in my 2018 is new for this year - not the same oven as previous years - it's very nice and not the el-cheapo one like I had in my Coleman. I has a porcelain toilet, LED lighting with motion activated sensors in the bathroom and pantry. It has auto leveling and black tank flush built in. It has a huge basement where I can haul everything I used to put in my truck bed - yes , that includes 42 gallon Thetford portable tank and my huge RTIC cooler, chairs, table, ladder - the list goes on. It is a rear living plan with an island, and opposing slides, a big screen TV with opposite theater seating that recline and have heat and massage. The heat register in the main living space is in the side of the island - no more dirt and sand traps. The refrigerator shelves have holding brackets that keep your food from rolling around. The cabinet doors shut securely and stay shut during travel. We do not use all of the available storage - and we are by no means minimalists! When I'm ready to go, the leveling system retracts and puts the king pin in the exact position when unhooked - so when it's done, I lower my tailgate and hitch right up, no up and down to get the height correct.
I'm a hard one to impress, but I am thoroughly impressed with the materials used and it's fit and finish. I went in it on Saturday after being closed up for a few months, and it still smells brand new inside. I've never been a fan of electric fireplaces, but this isn't just a decoration - it really heats the place up.
I bought from General RV in Orange Park Fl and had a very nice sales experience. So far, no service issues, but I have dealt with the service department for other things.
Of course, people will say that they are all junk, or I just got lucky. All I can say is that I really enjoy using it, and it hasn't let me down.
My advice is to go and see them. Take a tour, they will hook up a battery pack and demonstrate the options. I had a great salesman - will give you his name if you like.
On Edit - go to the Upcoming RV show at the Jacksonville Equestrian center - if you live in the vicinity. I compared to other units at the show and several dealerships and non came close - IMO of course.
