Welcome to the forum! Congrats on the new 303. We had a hard time picking between the 303 and the 337. We had very few issues to resolve with our rig after the first trip a couple weeks ago.
We're heading out on our second trip Wednesday morning. It is to a four day country music festival in in Florence Az. We have four adults on this trip, so it will be interesting to see how the guests fare on the sleeper sofa. We'll also get a chance to test the single A/C in our 337 because the temps on Wednesday and Thursday will be in the high 90's.
