I don't know if I still have the four-corner weights from our 1984 24-ft Holiday Rambler, 158" wheelbase.
What's the wheelbase on this 28-footer? That's about as far as they could go on an E350 unless it has a tag axle. Does it?
Getting axle weights is easy, CAT Scale at any Travel Center. Probably good enough to start with. Four-Corner is harder to find. Starting to wonder if the wheelbase is too short to put enough weight on the front axle.
A 1991 chassis will have 16" wheels. Are the tires Load Range D, or the more common E? D can only go to 65-PSI. If the front tires are inflated higher than actual load calls for, tracking can get flaky. Another reason to go weigh it. Weigh it as loaded and occupied for travel. If you tow, have the toad or trailer hitched up. You'll get Steer (front axle), Drive (rear axle) and Trailer (such as toad) on your report.
