GM 6.2 gasser questions

I'm gathering information for a woman friend who is in the market for a later 1T srw gasser pickup to pull a 5er. I used to be pro-GM for gas engines until I owned 93 and 2000 GMs and the plastic intake gaskets and their totally cr@p electronics on the entire cars ruined me on GM. I've been able to find good info on the 6.4 Hemi and the 6.2 Ford but not much on the GM 6.2. How reliable and fuel efficient are they? Does anyone have 100k+ miles on one and how did it do? Is it true they need expensive valve train maintenance at 100k miles. Any other real-world experience on them? TIA! Craig

    Ok, thanks! I've also read the 6.4 Hemi is not flex fuel but I can't find any more reading on that. So what do you do when e85 is the only fuel available? Craig

    The GM 6.2L is not available in the 2500 or 3500 yet, even though GM keeps saying it is coming. Their gas in the ¾ & 1 ton models is the 6.0L and there are very good reports on the later models, but NOT so good on the early to mid 2000 models.

    I have the 6.2L in what they called their heavy(NHT) ½T and am very pleased with it.

    No 6.2 motor for the 1 ton GM's. They are still using the very reliable L96, 6 liter motor in the 1 ton trucks.
