As it is, we travel near the maximum load capacity and that is with an empty water tank.

Dixielou,
Since the larger TMs have 2 axles, you have four 14" tires in the 3326k to distribute your load, up to about 4900 lbs. max. load capacity on your unit, with ~4400 lbs. on your TM axles (~4900 lbs. GVWR minus ~500 lbs. tongue weight). So that would leave you about 1100 lbs. per tire, well under the 1870 lb. per tire rating of the C rated 14" tires. Yes, it would still be better if they used 15" tires, but I would think the 3326 probably has the best "cushion" factor per tire than any other TM model, mainly because you are distributing the weight between tandem axles.
I guess my main concern is if you lost tire pressure in 1 tire, then the other tire on that is over its rated capacity....that could be a potential problem. The TMPS that rickst29 mentions above could help with that problem if a tire goes down slowly, or even if you aren't aware of a blow-out. I have the Doran system, and it is extra peace of mind during travel.
