I have the same vehicle and asked the same question and got nowhere! If full laden with the 'van fully loaded and using motorway speeds, my local tyre company told me that an increase of "a couple of psi" would be fine, as "those tyres are so darn big!" No other info was forthcoming from various forums and Toyota dealers.

I think 29psi is too low on the original goodyears - the tyres wear around the edges, especially at the front. I ran mine at 33-34psi and they wore more evenly.
I've switched the tyres to General AT2 (all tarrain, and snowflake marked) and find they work best at 35-36psi.
I have a 2005 LC3 and have always ran at 29psi - solo or towing. My previous Colorado was just the same. I have never had any tyre wear problems or stability. Our French trips are 3000+ miles - annual mileage 12000.
Have a look on your drivers door pillar. There should be a TIRE-LOADING INFORMATION stick on label.
This is a copy of my label.
225/70R17 108S front 29 rear 29 LOADED Front 29 rear 38psi
265/65R17 112S front 29 rear 29 LOADED Front 29 rear 29psi
They are the original Good Year tyres, and the label on the door pillar is the same as Mike put above - 29 in all situations, so I guess that's what I'll go with - it just seems low to me... Thanks for info all.
we have toyota surf and normal towing 28psi all round i use to up pressure to 35 as tyres stated to tow twin axle but found steering too light, so after lots of googling etc, i have left the front ones at 28 and up the back to 30, except i forgot last time and left at 28 all round we have a much better tow now and no light steering, always thought you had to up pressure to max for towing but have learnt alot now and as toyota has big tyres you dont need to go to max.
29 seems very low. I run my Toyota Surf at 33psi and found the outside edges of the rear tyres have worn more than the centre. I have now increased the rears to 35psi.
Tyre pressures are something of a grey area. The pressures stated by the manufacturers may not be the optimum if you change to a different make of tyre, ir even if you change the tyres to the same make if the tyre manufacturer has changed the construction slightly.
It is a good idea to monitor the way the tyres wear and alter the tyre pressures accordingly. It is also a good idea to increase the pressure in the rear slightly when towing.
However, for the percentage of time most people tow, this is not practical. Especially if going for a weekend. Realistically, who is going to increase the tyre pressures friday afternoon, tow to site, unhitch and reduce the tyre pressures to go shopping then pump them back up on Sunday morning and let them down again on Sunday evening?
With both my Landcruisers I have always replaced a tyre with the original Dunlop Grand Trek as they give such a quiet, comfortable ride. I am not into 'mudplugging' and have never had a problem on muddy sites or with the rare occasional snow we get down here in the SW.
Never had irregular Tyre wear using 29psi pressure.
