Congrats on your new memory maker from a fellow Bullet owner. They're great coaches with lots of value on a lightweight frame. So far, the only issue I have oustanding with mine is an A/C wiring recall from last year. I don't think the 17s are included, and I'm sure the dealer would have amended the fix prior to your walkthrough.
As far as "hacks" or ideas, there's
this sub forum that you can peruse to see how members personalize their coaches. Mine has been modded (
see here) over the last 11 months I've owned her. Last mod was installation of a MaxxAir fan, in preparation of our upcoming camping season.
If you have any questions, do a quick search as many of them been answered Nth times over. Otherwise, ask away and you'll get honest (sometimes biased) answers.
I'll suggest one mod you may want to consider as your first, tires! It's been a hot topic as of late and you'll see how important it is with trailers that are built by companies who dont prioritize safety margins. I'm outfitting my Bullet next week with new wheels and tires that add a significant load rating to the OEM components.
Again, congrats and welcome.
