I have a 2010 Passport 285RL that I bought this last March. After the first trip I changed out the OEM scissor jacks and bought 4 BAL 24" scissor jacks and an X-Chock. It is very stable. The BAL jacks are 10 times better! As for the 30 gal. tank the wife & I can make due for 4 or 5 days. Next to the tank under the bed (in ours), there is room for another 20 or 30 gal. tank. I may drop another one in and put a "T" in the supply line...50 or 60 gal. of water. Got to watch it with only a 30 gal. Black & 30 gal. Gray.
