Allegro Open Road Weight

I just purchased an Allegro Open Road 32CA, has anyone had theirs weighed. I would like to have a starting point for tire pressures until I can get it on a scale.

Congrats on the rig. Just about all truck stops will have a scale as well as moving /storage companies, sand and gravel pits, grain terminals, fertilizer sales places, some highway weigh stations and so forth. Weigh each axle and divide by 2 will get you close. If you want to fireproof it, look up the pressure required by your tire manufacturer and add 5 psi to account for possible side to side differences. If your axle weights call for pressures down around 70-80 psi, you may want to add air in 5 psi increments to stiffen the sidewalls and improve handling. These increases will not appreciably affect tire wear.

Until you start traveling in it, set your inflation based on your axle max weight ratings. But you really need to get your RV weighed to see how your RV's weight is biased front or rear. Also, if you ever attend any rallies like FMCA, Good Sam or similar, they periodically provide 4-corner weighing (for a nominal fee) for attendees that allows you to understand your side to side weight bias as well. All of this is important for when you load up and hit the road to be sure you're within all your weight maximums.

Robert41 - we have a 32SA, and loaded for the two of us, with 4 corner weight, tire pressure recommendation is 88 pound all around. This is for the 22.5" tires. Michelins.

Check your chassis weight, you either have a 22K or 24K. Best to get the rig weighed. I have a 32SA, I run 85 psi in rear duels, and 90 psi in front tires. I just had my front axle, rear axle, and toad weighed on CAT scale. They didn't have 4 corners.

Fully loaded with full water, full gas, all camping supplies and clothes, I was 22,340 lbs. I have the 24K lb chassis. Look up the Michelin Tire weight ratings for PSI for your size tires. With the 24K chassis, coach comes with 255/80R 22.5 XRV's.

Hope this helps...

We have a 2020 Tiffin Open Road 32SA with the 24K chassis. We weighed on a Cat Scale at 21,750 lbs with about 1/3 full fresh water and 2/3 full fuel tanks. Black and grey tanks were near empty.
