Thanks all, some good points I had not considered. I've ordered 4 Bilstein's and may replace tie rod end and possibly ball joints. Right now the camper is off the truck. When I load it in March it will likely stay on until next fall.
Time on truck vs mileage: Good point. Mileage will be more like 80%.
Shop bay height: Not a regular tire shop and has plenty of clearance, it's a specialty alignment shop.
Front to rear rake: Loaded, my truck sits almost perfectly level, no plans for airbags.
Front weight: I can't find my scale ticket but IIRC there was not much added weight to the front. I do sometimes carry a cooler/rod rack that adds significant weight, especially if I do real well fishing :B
Thanks again, I was curious as to what everyone else would do if you had the option.
