Triple 7Ks had a GVW of 20K and Triple 8Ks bumped that up to 21K. The pin box is/was the limiting factor. Now they are coming With the 8K axles/disc/LRH tires standard. This puts the GD toyhaulers far ahead of the competition.Huntindog wrote:
My Momentum has optional 8K axles and disc brakes, 17.5 LRH tires, a 12" tall frame, and is the first RV I have owned where the tanks actually hold what they are spec'ed at. This is my 4th RV over 30 years, and the best one yet.
Thats great, but I am not sure what the height of the frame has to do with quality. One would expect the frame rails to be larger on a bigger rig. A 12" high frame can be fabricated just as shoddy as a 6" high frame and when it comes to LCI that speaks for itself. I've yet to see a quality weld on an LCI frame and its a known fact they use cheap surplus steel whenever they can and the smallest/lightest they can get away with. You paid for the optional axles and disc brakes, what would you have gotten from Grand Design as "stock"? Are you saying that the stock axles and brakes are low quality? I looked at a 2021 Grand Design TT and it had OEM installed Lionshead Castlerock China Bombs.
If you will notice even the 7K axles in 2021 exceeded the GVW of 20K...A stark contrast to the industry standard of subtracting the hitch weight from the GVW to determine axle size.
A testament to GDs confidence in their frame and running gear is that they state the garage can have the entire CC loaded into the garage! My Momentum 398M has a CC approaching 5K!! I have a trip planned where I will load a Jeep into the garage. That would not be possible within the ratings of most of the competition
I haven't been shopping since I bought my Momentum, but at that time, they stood out from the rest. Only DRV, Luxe, and New Horizons were better in some areas. But none of them had the 18' garage we needed
