The bolt-on sliders in the companion guide handle most Power Wagon trail use. This weld-on alternative exists because a Power Wagon is heavy — around 7,000 lb at the curb — and when that much crew-cab truck pivots on a rocker against a rock, the mount carrying the load needs to tie hard into the frame. For a truck this size that actually wheels rock, the welded joint is the honest answer. It is also the one that puts heat into a high-strength steel frame, so read the frame section before you strike an arc.
A slider's job is to take the truck's full weight on a single point of rock and protect the long structural rocker below the doors. On a 4,000 lb Jeep a bolt-on does that comfortably. On a Power Wagon the same maneuver puts three to four thousand pounds through one contact point, and it arrives as a shock load, not a static one.
Two things fail under that. First, a bolt-only mount eventually elongates its bolt holes — the bracket works against the frame, the holes go oval, the slider develops a wobble, and the geometry that was supposed to hold the rocker off the rock stops holding it. Second, a bracket welded only at its face concentrates the load into a small area of frame rail rather than spreading it. A properly built weld-on uses three or more frame tie-ins per side with gusseted plates that distribute the load along the rail instead of into one spot.
Know your cab, because it sets the slider length. 2014 and later Power Wagons are Crew Cab only on a 149-inch wheelbase with the 6'4" bed. 2005-2009 trucks were offered as Quad Cab and Mega Cab, and the Mega Cab's rocker is substantially longer — a slider cut for a 2018 crew cab will not span a 2007 Mega Cab. Measure the actual distance between wheel openings on your truck before ordering; crew-cab bars generally run 60-72 inches.
This is where cheap sliders reveal themselves. Look for:
Then decide step versus tuck, and be honest about use. A kick-out step angles the outer tube away from the body and gives you something to stand on getting into a truck whose door sills sit high — genuinely useful on a daily-driven Power Wagon, and it deflects rock away from the rocker on a side-hill. A tucked bar hugs the body, preserves break-over clearance, and does not catch on a rock ledge you are trying to slide across. On a truck that sees pavement most days, take the step. On a dedicated crawler, tuck it.
The Ram 2500 frame is fully boxed and built largely from high-strength steel, especially on 2019 and later trucks. Ram's own body builder guidance is restrictive about frame welding and drilling for a reason: heat input into high-strength steel creates a heat-affected zone that is locally softer than the parent metal, and welds placed on the frame flanges (the top and bottom horizontal surfaces) sit where bending stress is highest. The practical rules:
If any of that reads as beyond your setup, the bolt-on slider is not a consolation prize — a well-designed bolt-on with a wide bracket footprint outperforms a badly welded frame-tie every day of the week.

Budget on the higher end for a Mega Cab. If a listing does not publish wall thickness and the number of frame tie-ins, treat that as the answer to the question you were about to ask.
Step to weld-on sliders when a heavy Power Wagon regularly loads its rockers on rock; the bolt-on covers everything lighter. Demand 2" x 0.250" DOM and three-plus frame tie-ins per side, weld to the rail web rather than the flanges, keep heat away from the fuel tank and factory brackets, and wax the frame cavity afterward. Pair them with the skid plate guide so the underbody is protected as a system, and see the bolt-on slider guide if welding is not on your table. Done right, this is the rocker armor that survives a 3/4-ton's weight.
