Congrats and welcome to the Intent 26M club!
I got mine in September. After having several Class C's, we decided to try an A. Now after 12 camping trips, I'm starting to get it dialed in!
I did the Cheap Handling Fix first, then the Safety Steer. I tried Bilstein shocks but took them off after one trip. They tried to disintegrate the RV! It was unbearably rough.
Some of the other mods so far are a new shower head, removed the glass shower door in favor of an adjustable rod and curtain. That added 7" of elbow room while showering and just swing it inside the shower when not in use. Huge upgrade.
Removed the dinette and put in a very comfortable reclining couch. The little table up front works great for me and the wife, so that was an easy decision.
Removed the overhead bunk and replaced it with an 18" deep shelf. Turned wasted space into fully functional storage.
I also added more kitchen checkered material to finish where Winnebago left off, then I covered it with a removable peel & stick backsplash.
I also added the same material to the bathroom counter.
I made a refrigerator latch to replace the ridiculous threaded knob.
Added stainless grab bars for the stairs. A lot of people find the stairs steep and I don't want to scrape anybody off the ground.
Under cabinet paper towel holder, stainless hooks for towels in kitchen, bath and shower.
Wire shelving in cabinets for more organized storage.
Replaced the thermostat with a digital model with better control.
I made a cord reel for the electrical cord and a metal holder for a box of gloves to tidy up the dump bay.
To further clean up the dump box, I'm adding a bumper next weekend to the rear to hold the "stinky slinky".
Along with the bumper I'll be doing a custom hitch to match the height of my Jeep Wrangler. I use the ReadyBrute Elite towbar set-up and love it.
Lined the outside storage areas with rubber to keep things from moving around.
A new mattress from Mattress Insider will be ordered next week. I put one in my last RV and it was very comfortable. I don't know how anyone can sleep on the stock one. A memory foam topper helps for sure, but it's no long term solution.
new radio with Apple CarPlay for the wife, a long with some rear facing speakers placed up front. The current speakers aren't so great, as you know.
At this time I will figure out how to properly secure that damn center pod so it doesn't keep trying to break itself apart bouncing down the road.
Replacing the stock rear view camera with a quality unit from RearView Safety. I've used this model in all my RV's with great success. It's sitting on the bench waiting for some spare time.
The taillights are very dim compared to my last RV. I found that the manufacturer makes the same units with LED lighting. So, there's a new pair sitting on the bench waiting in line.
Some more additions that should have come from the factory are a switch for hazard lights and a warning buzzer for the headlights if left on.
2 more house batteries to run the fridge so I don't have to use the generator while dry camping at a quiet beach or mountain campground.
A custom window screen for the emergency escape hatch for better summer airflow.
It's a never ending list.
