Is it worth investing a bunch of money for a custom hitch set up for a '98 with 125K mileage? Having owned this car since 2000, we had planned to drive this car into the dirt and caring for it accordingly (ie: new timing belt, tensioners, cv boots, brakes, rotors and tires). But we don't want the demise to happen in the middle of the family vacation.

Knowing we'd be towing right at the upper limit of the Volvo's capability, we purchased a Trailmanor travel trailer (about 3300 pounds loaded and roughly 350 tong weight). To our dismay, we discovered the only 2 inch receiver hitch assembly for the XC would have to be fabricated, allowing for the weight distribution hitch and anti-sway system to be installed. Additionally, the trailer has electric brakes which would be controlled via an electronic brake controller. We've found a very reputable RV shop in San Diego that'll do the work for a total of $1550.00.

That said we've talked to our Volvo mechanic of many years and he's concerned we may eat up our transmission towing through the mountains (is more concerned about the downgrades). Additionally he cautioned about messing with the ABS system as a new computer would run $700-800. The RV shop said the electronic brake controller wouldn't interact with the ABS system; rather it picked up the electrical signal going to the brake lights and utilizes an accelerometer to regulate inputs to the trailer's brakes.

We're not concerned about being the quickest folks up the hill, and we thought the electronic brake set up would limit the stress on the transmission coming out of the mountains. But with all the conflicting advice, we're trying to decide if we should move on to another tow vehicle? Realistically we're only talking about a couple of annual trips through the mountains, with the majority of the trips on relatively level grades.

So do we move on to something else, or hold our cards? Any advice would be much appreciated.

Your XC is NOT rated for a class 3 hitch.
The cost to install that on your XC is nuts on a car that's worth (wholesale MAYBE all of $3000)
You DO this and I can guarantee your tranny will fail quite prematurely.
You also forgot to add $$$ for the (necessary) tranny cooler.

(BTW ABS modules now cost less than $100 to rebuild them)

Despite some of the neigh say’rs, based on other postings we decided to go for it, having a custom hitch fabricated for our '98 XC. Our travel trailer has electronic brakes and we installed a brake controller on the car. Additionally, we're utilizing a weight distribution hitch to spread out the trailer load uniformly along the frame of the car, preventing the front wheels of the car from rising).
So we'll keep you posted on our progress. The first big trip through the Sierra’s will be in the spring. They way we see it, we've owned this car for 12 years and now we're going to start putting the XC part of its capabilities to use!

All the best,

put in transmission cooler - the biggest that will fit - have it on a thermostat - even a pusher fan if you have the space - you can also cool the bevel gear - but you may not need that - If you have to PM me - there is a trick way to do it but its not cheap - but it will run cool.

One trip into the mountains under our belt! Haven't added the additional transmission cooler (though did change the transmission fluid before the trip), we just take our time up the steep grades not letting the RPM run to high. Not the fasted tow vehicle up the slopes, but we keep chugging and get there!

Thanks for the support and we'll keep you posted.

Departing from San Diego, we just returned from a beautiful week in Yosemite. The Volvo pulled our Trailmanor (about 3500 lbs) to our 7500ft camping spot with no problems. On the way up, we took our time, staying below 3000 rpm on the majority of the big grades. On the way down, the electronic break controller took care of the rest. At 130K miles, we couldn't be happier with this car. Northern rim of the Grand Canyon, here we come!

Be careful to keep the tongue weight down. I'm pretty sure my 98 XC70 rear driveshaft center bearing wiped out as a result of the car being driven about 7k miles with a very heavy load of tools in the cargo bay along with sometimes pulling several hundred pounds of stuff in a utuility trailer. The car was definitely squatting a bit which no doubt put a pretty good misalignment angle on the mid shaft u joint and the adjacent middle bearing rubber.

The extra load may have stressed the carrier bearing more but the suspension height due to load would have no role. The independent rear suspension puts the diff in a fixed position regardless of ride height.

Absolutely correct Cattlecar....must have been thinking back to my son's old 83 240 Turbo with a two piece driveshaft and a live rear axle....that car always rumbled a bit on acceleration with a full paassenger load.
