Hi fraim,
Good to see another Aspect 26A owner. Ours is a 2007, purchased about 10yrs ago. I was led to believe (by the salesman) that we should average 10mpg. I have seen others who claim they do. I must be doing something wrong because we get between 7.5 to 8.5 mpg not towing (once I got 9mpg down hill with a tail wind). Now I see people with class A units who say they get that much. We cruise at about 60 mph. I use cruise on flat lands and use a gentle throttle going up hills. It is what it is. Our unit is very comfortable to drive and it loves to cruise at 70 to 75 mph, but the mpg drops down closer to 6.5 to 7 mpg at those speeds.
I like that we can take it nearly anywhere because it is only 10ft 5in high and 7ft 11in wide. We do check clearances for tunnels on the back roads.
Maintenance: We lube the front end every 20K miles. Working from memory...think there are 6 grease fittings. We also have the front bearings serviced every 20K miles. We use high quality synthetic engine oil and change it every 5K miles or once a year which ever comes first. Haven't reach the tune-up mileage yet. Coolent flush will be our next service. I had brake lines flushed, and front calipers serviced. If it sits too long and you make a panic stop the caliper can lockup. Just enough that the steering pulls to one side. You know there is a problem when you see smoke. That was about a $500 mistake. Make sure our air cleaner is clean and have the fuel filter replaced on schedule. We always try to make sure we have at least 1/3 tank of gas. Gas cools the fuel pump.
Good strong engine. We have traveled Coast to Coast, from Mexican boarder to Alaska, visited a lot of the Canadian Provence's Good rig, well built...no worries traveling in it. Oh, and it has a hard roof, not fabric. No leaks (just check seams once a year).
Only complaint: It rides rough: 26ft motorhome on E450 chassis. We checked the weight and adjusted tire pressure lower, but is still a rough rider.
This is probably going to be our last motor home. Good size, easy to use, looks good, likes to cover ground. Expect it to last many more years.
Happy trails
