Hello Duane and welcome. Our MH's are very similar as you probably already know. We have camped around 30 nights so far and loving our 35SK. We also have a handful of minor issues. Our dealer has taken care of all but two of them so far. There are numerous threads on fueling difficulties on the 33SW models on other forums. From what I gather, seems the problem can be resolve by reposistioning the filler vent tube so that it is above the actual fill tube, not allowing fuel to enter the vent tube while fueling. Fortunately mine fills just fine. I hope they fix it for you soon. Good luck and many safe miles to you.
Rudy, Jenny and Garrett
