No, a V10 can handle 285's/3:73 just fine. Keep in mind that we are extreme cases around here, generally speaking. Sportsmobiles and campervans are generally loaded to the hilt and have all sorts of heavy and un-aerodynamic racks, etc. and also they are toys for most the majority of us. We modify them and try to make them quicker and stronger and spend money on them just because.
There are plenty of 5.4's pulling lots more weight in tougher conditions all over the nation and the world for that matter. The V10 is a very strong engine, regardless of gearing. No way I would bother changing gearing until you think you really need it, which may be never.
The tranny may hunt a little more after your tire change but it's fine if you can live with it. You might not mind it at all. Two cheaper and easier things you can do for any van is to use the tow/haul setting more and/or to spend $600 (half the cost of gearing) on a 5-star basic RV tune (SCT tuner).
Every time I start thinking my V10 needs a little more power I am reminded that it really doesn't by getting passed by a class C motorhome with some clueless citizen in it who is simply voting with their right foot. Apply throttle and RPM. The V10 is a beast of a motor with any gearing.
