My Grand RV forum

Hi I have just found this Grand Design group, glad i did. Just a quick question why is there no Momentum travel trailer group? Or is under another group? I have owned my Momentum G29 for 6 years. After first year I learned about the MorRyde independent system and had a setup installed. Best money I have spent on trailer. It is a new trailer. Anyone else have the same reaction. I hauled a Harley 2 wheeler for quite awhile and after issues at Sturgis rally I decided to quit the 2 wheeler... Read more

Greetings, GD members. We recently had a tire blowout on a Goodyear Endurance tire that caused quite a bit of damage. The blowout damaged the J-wrap/skirt, the fender above the tires, and the area underneath the floor. It also broke off the valve stem on the tire in front of it, causing me to lose the TPMS sensor. To make matters worse, the tire debris struck the stabilizer jack behind it, breaking off the jack foot and damaging the wiring. I replaced the foot with one... Read more

We purchasd a 26 Momentum toy hauler brand new in November. Since then it has spent more time in the shop than out, and they are the worst about approving any kind of work. I'm sure we're all aware of the garbage fresh water system they use. We fill our tanks, but the overflow acts like a syphon, so wer have less than 2/3 of a tank when reaching our destination. What's the point of water tanks if they don't hold water? We have a leak in the fresh water tank, and they gave their authorized... Read more

Can anyone recommend a source for replacement trim. I’ve attached some pics but it fits in a channel running the front sides under the right side cam/light.

Hi there! I have a 2027 influence 5th wheel with the Moryde independent suspension and disc brakes from the factory. Great set up but I’m finding the disc brakes have a terrible squeal, even after several hundred miles of towing. It seems to be most noticeable when moving slowly from a stop and at low speed (say 5-10 mph)… I’m not noticing any noise at higher speeds. The noise fades as I apply the brakes, but comes back when the brakes are released. Does anyone have any ideas on the... Read more

I own a 2025 Reflection 337RLS. Does the seven pin connector go to a junction box on the RV? I see the wires go into a spot but would prefer not to take it apart.

We purchased our Grand Design Momentum fifth wheel 328G TH new in 2020 and recently developed significant fogging between the panes of the large main window on our main slide. There also appear to be water drip marks between the panes, so it’s more than just a little condensation. Feels like you are looking through pre cataract surgery eyes. We’ve been told the window needs to be replaced, have been told the seal may be broken and may not be able to fix the problem. Grand Design quoted us... Read more

I have a 2021 Solitude 345GKR that I bought new in 2022. Recently the living room Airxcel thermostat failed. Fortunately I had a spare thermostat. The replacement thermostat, same model, had a mounting plate which my original one did not have. At the factory they took the back of my original thermostat off & screwed it to the wall & then snapped the front of the cover back on. They must have had no mounting plate (either lost or just missing). They drilled a hole through the back of the... Read more

Looking to buy 2600rb located in South Texas, Does 1 AC unit adequately cool thus RV ok ?

My Solitude living room ac will reach temperature & shut off. After 3 minutes it starts up again & runs till it cools down & then shuts off for 3 minutes. This continues. As many of you know there is a 3 minute timer on the roof unit which will not allow the unit to restart for 3 minutes. The thermostat comes from the factory with a 1 degree temperature differential. I would like to change it to 2 degrees. There is a procedure to do this which involves opening the thermostat back cover... Read more

Our valence with the roller shade inside has come loose on one end. Anyone know the correct sequence to remount it? The screw we need to put in is impossible to insert without taking the whole thing apart. Any ideas?
